No, not at all. Jellyfin you’d have to setup a proxy or some kind of VPN like tailscale for the remote client to be able to access the media. I started to try and figure it all out when I first set up my server but as I have said in another reply j dont really care to waste the time learning how to do it in a secure manner and minimise the friction on my other users so I dont know the ins and outs but jellyfin you absolutely can’t just tick a box and share a library.

Also jellyfin meta data analysis was shit compared to Plex and so I’d have to spend even more time actually managing the server that I dont have to do with Plex.
