I think you're unlikely to have a very good experience with Tailscale behind CGNAT if you're doing anything high bandwidth like video streaming from a Plex/Jellyfin server.

AFAIK Tailscale only supports 2 modes of connection: direct connect or relayed over WebSockets with their DERP protocol. CGNAT is going to limit you to DERP, which is not designed for transmitting a lot of data. For one thing, that could get rather expensive for Tailscale.

Oh yeah it's not going to be very fast, but for general usage that doesn't involve large transfers it's fine.
