You’re more of an expert in home-server stuff than me, but here’s what I do and my reasons why, maybe they can help you find an answer yourself.
I’ve chosen Arch for my homeserver (contrary to most people prefering Debian) since:
- I’ve been using it for years and know a lot about it, so maintenance isn’t an issue at all.
- Newest software = latest bug and security fixes, features etc.
- the Wiki makes installing anything a breeze and many questions and issues are already answered in the arch forums
I don’t use a docker image and I don’t see its necessacity (again, you know better then me). I’ve seen however servers that use NixOS because they can have the whole infrastructure/system in a git repo, which makes moving to a new server easy and without issues, which is not your case since you’ll be running it on the same machine.
I’ve never used proxmox but if it’s specifically built for what you’re looking (ie. home server) then go for it even if it’s overkill. For me personally, Arch works great as a server.
F-Droid is the way
