How to Use Local IP for Services when at Home? (mander.xyz)

So I have some services and wireguard running locally on a "home" network. I also have wireguard, a DNS resolver, and a reverse proxy set up on a remote server. Since I don't want to expose the home IP to the public, to access my services I connect to the VPN on the remote, which then forwards my request home. But this means that when I'm at home, connecting to my local services requires going out to the remote. Is there some way to have the traffic go over the switch when at home, but go over wireguard when away, without having to manually switch the VPN on/off?

I could move the DNS resolver (which handles the internal names for the services) from the remote to the home server. But then similarly every DNS request will need to go through both the remote and home servers, doubling the hops. I'd like to use my own DNS server at all times though, both at and away from home. Which tradeoff seems better?

edit: thanks for all the suggestions, I'll look into some of these solutions and see what works best

And so when away do you just directly connect to the external IP and do port forwarding?

Actually I am behind CGNAT so when away I connect to my VPS that has a nginx pointing to a wireguard endpoint to the internal server. Wireguard is also managed by opnSense but that's a choice, not mandatory.

When home, my VPS ip gets rerouted on port 443 (and 80, mandatory for let's encrypt) to the internal ip of my server.
