Question about traffic using Cloudflare tunnel (sh.itjust.works)

Let's say I setup some subdomains and then point them to my home server via Cloudflare tunnel.

If I use one of those subdomains from my personal PC on the same network as my home server, to watch a movie for example, is all of that traffic going out to the internet and then back? Or does all the traffic stay internal once the connection has been made?

Uhh, this might be true for WebRTC, except not much uses WebRTC other than for realtime streaming/calling. Jellyfin for example is just an mp4 stream over http; and http(s) will only use the IP in the DNS record. I'd like to see a packet capture if you are certain something is switching IP.
