Old School Runescape if you like grinding. But you might never quit if you get hooked :')

What’s the software support on these like? 2 years and then just lineageos after if you’re lucky?

I have been very happy with desec.io, they are a nonprofit based in Berlin.

Thank you everyone for the helpful replies!

Nextcloud + Nextcloud Music App is also a good solution. The app supports subsonic too, so it can be used with a few different apps.
