No reason other than the fact that you need extra steps to get Jellyfin working in Fedora.

If you have the patience and time, as I mentioned, you can still use Jellyfin in Fedora.

Debian, Ubuntu and Fedora should be good (in that order); I’m not very aware on truenas to give an opinion, but it seems it will work just as well from other comments.

I personally use Fedora, and it’s been a solid experience too, with the only gripe bring SELinux. I required a fix for SELinux, but it has worked flawlessly since.

However SELinux might make it annoying to work with containers, so you could consider either switching it off, using another distro or using appropriate configurations to work with it correctly.

A smile where the person is so full of it that you want them to “eat shit” (you hate it)

A regular ethernet cable is sufficient in most cases. Except for ancient network cards, most newer ones know to flip the wiring to be able to communicate between two computers.

The only thing is that you need to set the network options manually in both computers - set the IP address and subnet. Then just transfer it using any network file sharing protocol. (Windows already has file sharing, Linux you can use sftp, or use a http server)

Edit: Looks like you asked specifically for USB. Sadly that is not possible specifically with usb since both devices are “hosts”. I provided this solution since ethernet cable are also very common and cheap to use

Apache httpd if php is involved. Otherwise, nginx.

Both are highly reliable and efficient.
