Apart from the Pi4, to upgrade, I know that I will need a bigger power
supply and a HDMI adapter lead, but after, things are a bit vague.  Can
I get away with the Pi4 without any additional cooling, or do I need a
heat sink or fan, and if so, how do they get on with the hat ?  The
space it is in has had a temperature range of -1 to 40 degrees C, the
mean across that time is about 15.5C.

40C is quite a high ambient temperature. If you are going to run the Pi
4B hard with the likes of matplotlib, passive cooling my not be enough
to stop it throttling. One of mine has a large heat sink case with no
fan and never goes over 60C, but that's at a 20C ambient. For 40C
ambient, I would recommend a fan case, go for a 40mm fan if you want it
to be quiet, 30mm ones can be noisy.
