Fedora is a Desktop OS, not a server OS. Proxmox is ok, but overkill for your needs.

Ubuntu server is what you’re looking for. 12 years of security updates, officially supported livepatch (so no reboots after even kernel updates), and official support.

Hire a professional. This is not a safe thing to do yourself. Any server needs to be professionally secured.

Nope replaced it with nextcloud years ago. Install Ubuntu LTS and then:

sudo snap install nextcloud-server

It’s installed!

Or you could use Plex and jump through zero of these hoops

Ubuntu and it’s derivatives have the best Nvidia support.

You don’t. You use Debian, Ubuntu, or redhat.

You just answered your own question

Seems reasonable. I’m a lifetime Plex pass holder, so it won’t affect me or the one person I let access my server lol

Don’t bother asking for help without including the EXACT command you ran and the EXACT error you received.
