Jellyfin and uptime kuma

If you mean, NPM (Nginx Proxy Manager), shouldn't be a problem. A lot of other people have used NPM with proper domains. Shouldn't behave any different with a NoIP DDNS domain.

Yeah NoIP will work fine.  That's also where I started before I bought a dedicated domain.

Is a reverse proxy really more secure than just a port forward to a machine with a firewall?
I can't seem to find any huge differences other than convenience. I already have my IP behind a domain.

Yes.  There are attacks against the TLS/SSL handshake process that Jellyfin isn't hardened against.  Nginx/Apache/Caddy/etc. are.  Plus configurability and extra https security parameters that Jellyfin just doesn't have.
