The vps is the wg server and my home server is a client and it uses pihole as the dns server. Once your clients hang around for a minute, their hostnames will populate on pihole and become available just like TS.
You do have to set available ips to wg's subnet so your clients don't all exit node from the server, so you'll be able to use 192.168.0.0 at home still for speed.
As for NPM, run it on the proxy, aim (for example) Jellyfin at 10.243.21.4 on the wg network and bam.
