i want to remotely ssh to my home server, and I was wondering if I could just forward port 22 with disabling password login and use pubkey authentication will be safe enough?

The benefit of wireguard^ is it runs over udp and won't respond unless a peer with the right key hits it. ie a port scan won't reveal anything because there's no tcp port open to handshake, and wireguard won't respond to junk data coming in.

^ Most VPNs run over udp. But i'm not sure say OpenVPN will respond to random crap, it probably won't but i don't want to state categorically that it won't.
