making a decision - he gave the example of buying a car. It's also
common for someone to want to "sleep it on it" before making a
decision where the decision is important but it is not clear what
decision is best. If a decision is essentially predetermined then what
is the point of that time and effort or sleeping on it?

Do you not see that this argument depends on the belief that there was
an *option* to make the decision earlier under different conditions
(lack of 'thinking it over' and/or 'sleeping on it'). IOW that free will
exists. You are 'begging the question'.

It's actually the complete opposite, I am starting with the assumption
that there is no free will and asking what then is the point in
deliberating over the various options. You seem to be taking things a
bit further and saying that if determinism exists then there aren't
any options to begin with but that is just a variation in emphasis, it
doesn't address the question of why we spend so much time pondering
those options when they don't even exist.

Consider writing an algorithm controlling a robot walking down a path.
The robot comes to a fork in the road. Does it take the left fork or
the right fork?

The algorithm can have layered complexity. Scan left, scan right,
process data. Simple-minded algorithm scans 1 sec each way, sums up
some score of positive and negatives and picks the best. If it's a
tie, it might kick the random number generator into gear.

Alternatively, it can get into a loop where it keeps scanning left
and right until one "choice" passes a threshold for "better" that
is not just a greater than sign, maybe 10% better or such. From
the outside, this is "pause to think". With a little imagination,
one can add much more complexity and sophistication into how the
robot chooses. It can be dynamically adjusting the thresholds. It
can use it's wifi connection to seek external data. It can find that
its wifi signal is poor at the fork in the road so back up to where
it was better.

Map "go home and sleep on it" to some of that or to variants.
Map it into Don's words. The robot could not "choose" left or
right until its algorithm met the decision threshold, i.e. it
didn't have a legitimate option yet. (hopefully he'll correct
me if I have abused his intent too far)

To an outside observer lacking full knowledge of the algorithm,
it looked like it had a choice but inexplicably hesitated.

 It is *you* who have missed the point. What you have described above
is an algorithm to process data and arrive at a decision; what I was
asking about is why we delay once all the information that is
available or likely to be available *has been processed*. Once all the
information has been input in your algorithm there is no reason for
the processor to continue analysing unless you add in some sort of
rather pointless "just hang about for a while" function; no matter how
many times your algorithm runs with a given set of inputs, it will
reach the same decision. One exception to that is your suggestion of a
random number generator when the two options look more or less equal
but your problem is that that randomness is very antithesis of
determinism.

I think that makes some big assumptions on what information is being processed and how the processing actually works (and what that implies about how long it can take & what conditions cause it to terminate).
Consider the common decision-making advice of "flip a coin to make the decision; how do you feel about the result? You have your decision". It doesn't always work but I think most would agree that it can. It's also very analogous to the case of your wife changing her mind after having made the choice.
It also seems clear that this method *does* generate new information, to the conscious self at least. The reason to do this is that a critical component of a decision is *how we feel* about something, and this isn't something we have full conscious clarity on. New events like the coin flip might not add information about external aspects of the decision but they can add information about *us* and that can impact the decision.
Or more analytically if you imagine decision-making as a back-and-forth between two different information-processing mechanisms, the one we consciously experience as thoughts and the one we consciously experience as feelings, then ISTM that accounts for the phenomenon neatly enough. Decisions where "feelings" provide a strong answer but "thoughts" don't, or agree with "feelings", are easy and quickly made. Decisions where "feelings" give a weak answer but "thoughts" give a strong one are slightly slower & harder because "thoughts" are a slower & more effortful process, but still quick enough at conscious scales.
The really long-winded or difficult decisions are those where both "thoughts" and "feelings" give weak or ambiguous answers, or they give answers that are at odds with each other (and it's possible that second is just a case of ambiguous "feelings" - that "feelings" always carry the day & situations where "thought" seems to override "feelings" are actually a case of "thought" identifying a contradiction between different feelings & resolving it). What goes on with those isn't just "information processing", or at least the processing is a lot more involved than that bloodless term suggests. It's a lengthy exchange between the thinking brain coming up with scenarios, submitting them to the feeling brain for evaluation, incorporating the result into new scenarios & repeat until it's kicked the feeling brain into a distinct coherent preference.
If we collapse all of this into "an information-processing robot" then all it means is there never was a point of "all information has been processed". The sleeping on it is information processing; the choosing curtains then thinking better of it is information processing, information is being processed the whole time. And in fact could keep being processed forever, with different cognitive processes being required to make the processing stop (for example I don't recall the name of the phenomenon but I'm pretty sure it's a thing that picking an option causes us to prefer that option more than we did before. Presumably it says something that this phenomenon wasn't enough to make your wife feel good about her choice, thus justifying her change of mind).

The same general retort will apply to most all of your retorts.

 In that case, it would have been useful for you to retort to the
example I gave about my wife in the second half of my post which you
ignored.

An added thing to consider is where "consciousness" comes into play.
All the data the robot is scanning can be processed by sub-processors
that generate most of the information needed to produce a choice
before the central processing algorithm distributes instructions
to the subroutines that activate whatever it is the robot needs
to do to locomote down a path. Fill in the blanks.
