Jellyfin is a fork of Emby before they closed the code, so most likely everything you have on Emby you would have on Jellyfin but without the worry that tomorrow Emby will pull a Plex onto you. Up until a while ago they were so alike that you could use Emby client on a Jellyfin server, not sure if that’s still possible though.

I used to use Arch, now I use Nix, so that checks out

I spent a while getting Ansible to be able to setup and maintain my server(s). And ended up not using it as much as I should, mostly because the computer I used to run Ansible from became a “Steam Machine” so I’m rarely sitting on it with a keyboard now and I don’t want to have personal info and keys on my work computer.

But it was a good learning, and useful while I used it. Now I just use ssh and compose files directly.
