Can you use the VPS to create an exposed network and retain the jellyfin server on the device at home? I did that in university in a similar situation
I use plex, I configured plex so server was “located” my VPS address and the VPS routed back to my computer (which was behind a double NAT so I couldn’t port forward)
I believe the reddit thread about it discussed how users were hosting child abuse material on ports with their IPs
