I wonder if there's some difficulty in getting the shift right on
these 11/12/13 cog cassettes that's making the wireless shifters
popular. Are they more precise?

Don’t believe so no is mechanical 11/12 speed stuff certainly. Is more
narrow but no mechanical aka cable can and does work fine to the best of my
knowledge.

Wireless does do away with electronic cables and the routing of those.

The motor/electronic controls are significantly more accurate and repeatable than a cable system. It's not so much of an issue with ten speed and fewer since you have more tolerance (aka'slop') in the system, but as the tolerances grow tighter the simple psychical changes in the system as it wears would mean more frequent adjustments. Enough wear in the system can result in mechanical hysteresis which would make accurate shifting all but impossible.

Electronic shifting (wired or not) removes the biggest variable in shifting accuracy and repeatability - cable wear. Also, electronic systems can use feedback to fine tune derailleur positioning to compensate for any mechanical wear in the derailleur and chain.

Theoretically, electronic controls are vastly superior to a manual control system. However, many people are of the opinion that it's just something else to go wrong (and for the most part, inherently unrepairable). They aren't wrong.

 Much agreed.  Add in complex failure prone cable routing on several modern design frames (not only rear suspension).
 And yes again that removing cable troubles doesn't mean removing control troubles altogether!
 IMHO electronic shift advantages are not specific to 11-12-13 systems in that I have a few customers running those with friction shifters without complaint.  But electronic shifting is indeed much more precise and repeatable for any derailleur system.
 

There is an inherent yet unspoken advantage to friction shifters - they can be 'trimmed' to accurately alight the gear selection....not so easy with an indexed system.
