Really wanted to like Jellyfin but it just can’t replace plex yet for me. Once it’s developed a little more I’ll definitely take another look since plex is shitting the bed.

Definitely support this recommendation. Having switched to this from windows a few months ago I can say that it is very stable (after I fixed secure boot issue) and very pleasant to use. Solid built-in apps. Tried GNOME first. Its design was good but just not for me.
