Mine runs Arch (btw) and hosts a handful of things using Docker. Adguard Home, http://mckinley2nxomherwpsff5w37zrl6fqetvlfayk2qjnenifxmw5i4wyd.onion/, and some others. NFS, Flexo, and Wireguard (peer and bounce server in my personal network) are outside Docker. I have a hotkey in my window manager that spawns a terminal on my server using SSH. It makes things very easy and I highly recommend it.
I am thinking about replacing Docker with Podman because the Common Wisdom seems to say it's better. I don't really know if it is or isn't.
Also, how much of your personal infrastructure is on IPv6? I think all the software I use supports both, but I've mostly been using IPv4 because it's easier to remember the addresses. I've been working for the last couple days on making it IPv6-only.
