To mitigate the effort to maintain my personal server, I am considering to only expose ssh port to the outside and use its socks proxy to reach other services. is Portknocking enough to reduce surface of attack to the minimum?

Have you met my friend Tailscale?
I used to SSH into my server and proxy out from there. Then I learned how shit of a solution that is for daily use and set up a vpn like a normal person.
What kind of port knocking just going to ports in sequence? Or someone wrote one that looks for a key signed and is supposedly not replayable.
Instead of ssh I use wireguard directly. It’s a simple protocol based on public/private keys with great performance and security.
Wireguard is stateless and establishes connections really quickly on demand. This means the battery isn’t impacted even though it’s always on, since the VPN doesn’t have to maintain a constant connection. At least that’s the case if your routing only a specific subnet (e.g. 192.168.1.0/24 and not all traffic through it 0.0.0.0/0).
I use a vps running openvps. Then i only allow ssh access from my vpn ip address.
