Wow, I did exactly this yesterday.
Went super smoothly, and Android, Google TV clients work fine, as does Chromecast. Android Auto support not great but at least did play the music I told it to which is the main thing I guess.
Not any good desktop clients that aren't Electron garbage, but Plex is no better here.
First party docs for setting up Nginx in front of Jellyfin were Really Freaking Good. Like Arch Wiki levels of good.
Put the lot on a Tailscale IP and now I have access to my Jellyfin from anywhere - including, surprisingly, from my chromecast where the the Tailscale app installed without a hitch.
There's an interesting comparison actually between Plex and Tailscale.. both are sorta-in-the-universe-of-open-source-but-not-actually... but I know which one I trust and which one can go and get bent.
