+1 for Bazzite (or another one from https://universal-blue.org/ ), very hard to destroy, if an update breaks something just choose old install during boot and wait a few weeks before trying again. I am kinda savvy but don't really need (or can 😸) tinker with the system.
Where are you based? Maybe someone from https://endof10.org/ or another local hacker grouo could help you in person. There are regular install parties in my city.
