Might look into the pangolin project if what you’re trying to do is expose services from your home network over wireguard to a reverse proxy on a vps.
The software suite is basically wireguard, traefik, and auth middleware wrapped in a trenchcoat. Much simpler than rolling your own implementation, but there has been recent controversy with the project over locking “basic” existing features behind a paywall after the project got popular, though after public backlash they’ve backpedaled on that iirc.

Edit: Just realized you said tailscale. Above recommendation might be a deal breaker depending on your reason for wanting tailscale specifically
