That’s exactly the use case for “tunnels”: allowing public, incoming connections behind CGNAT.
Wireguard requires a public IP on at least one side of the connection and only allows private access. If you want to host a blog or website AND you’re behind CGNAT, then a “tunnel” service is a very easy solution.
