I use WireGuard and ssh together.

On my two VPSes I have one of them run a WireGuard server, and both of the VPSes have their sshd bound to the WireGuard interface only.

At home I have a computer running a WireGuard server. Two of the other computers at home are clients of both the WireGuard server at home and of the WireGuard server VPS. I can connect directly to the WireGuard VPN at home from anywhere and ssh into the other machines on their WireGuard interfaces of that VPN, but if the WireGuard server at home is down I can connect via the WireGuard VPN that runs on my VPS and still ssh into the other machines at home that way.

I also have WireGuard running on a physical server in a data center that I manage. On that server I use WireGuard only because it makes connections much more stable than connecting via ssh directly.

My three different WireGuard servers all use different private range IP address subnet ranges, so there is no conflict. I use WireGuard for communication between my own hosts but not for tunneling other traffic.

WireGuard is great and the perfect solution for a small number of machines at least. And I am sure that if you have a lot of machines you could come up with some suitable setup using WireGuard even then.
