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

You might find the techniques used in Network-Aware Firewall useful. You can use firewall configuration to handle connections differently depending on whether you are connected to your home network or not. Or you can use the same techniquest to do other things, depending on network connection, like bringing up your VPN or not; modifying DNS or hosts file or not; etc.
