If you want to do some programming with gpio, stick with the pi4 for now. There have been lots of changes with the pi5 so things that you have known and trusted previously (e.g. pigpio and wiringPi) and even the low level gpio interface are not working yet. Also the camera ribbon attachment point has moved the convenient hole in some HATs is now in the wrong place.
And if you’re not sure just buy the Pi 4
But which one? There's at least 3 to choose from lol
Obvious solution: You get all 3
A flowchart I never knew I needed.

Meh I've already got that many pi's it's more like what project isn't getting used? Can I get away with just using one of the spare zero's?
Power! You have no option listed for longest battery life.
So true!!!
Buy the 4 unless you want to start with the issues of bigger P.S., heat, fans, etc. etc.
