When I stream things inside my own home, is that traffic all being routed out through the internet, or is DNS smart enough to know it's local traffic and keep it on the local network?
It depends. If you have a split-horizon DNS and your internal clients resolve the internal IP address of your server when querying for jellyfin.mydomain.com, then your router is not going to see the traffic (assuming client and server are in the same VLAN).
If your internal clients resolve the public IP address of your router, then the traffic will go to the router and it will have to do what it's known as NAT loopback or NAT hairpin to send it back to your server.
