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?

If you only want to provide ssh access to one host, sure. If you want to provide other services, on multiple hosts, then you’re either making it a jump box or a proxy, while a VPN would provide direct access (or at least as defined in the firewall and routing rules).
