Python / FastAPI will be better than Java in your situation and is easy to learn. Go should be even better and is also relatively easy to learn!
I own two Raspberries 1, a Raspberry 4 8GB and a Raspberry 5 8GB. I wouldn’t recommend the 4 as a full-fledged desktop replacement, but the 5 has been very smooth so far.
I’m currently using the latest Raspberry Pi OS Lite and installed KDE on top.
I have spent a lot of time playing GB/GBA games and Advance Wars is among my favorites. I love the “hot potato” mode for playing with a friend with just one device.
