At this point you are pretty close to just being able to use your VPS for whatever you wanted to do access remotely. I have tried a ssh port forward solution earlier, but the connection fell down, did not always come up after boot and was generally unreliable. I found wireguard to be much easier to set up and highly reliable. It's in my own opinion not that hard to set up either, there are plenty of guides. The wireguard project docs are also quite good.
