there is no gui component to the jellyfin server so no benefit in a desktop therefor no need for a remote desktop
(outside of the web gui which can be managed from Any browser, not desktop specific)
personally, i use portainer+docker+jellyfin server because i already use docker for other containers for various things and it works perfect
i would recommend this for portability, any time you want to rebuild or relocate the server install it is exceptionally simple
if this is a dedicated machine for jellyfin server; it could be just as easy to go bare metal and then no need for the extras of docker or portainer, pretty sure this is still fairly portable as long as you setup your mount paths correctly
