This is very cool, but you should not use Cloudflare Tunnels to stream media. This is forbidden by their terms of service (or at the very least not the intended use of Tunnels and they may disable your service). Use Wireguard or Tailscale instead.
Personally I'm switching to rathole+traefik, weirdly something I was researching and experimenting with in the early hours of this morning (I have now not slept and have to go to work).
This let's you use your own domain for your tailnet, isn't the funnel but - but isn't it even better? Unless you actually want a publicly routable domain name, then you're back some hosted ingress I guess
Since https://blog.cloudflare.com/updated-tos it is not completely clear if you disable Cloudflare's cache indeed. Still the terms are unclear enough that they could cut you out, and I'd feel uneasy exposing a Jellyfin instance publicly, but that's just me :)
