I’m not talking about your home computer. Obviously your home computer shouldn’t have ssh exposed to the world on any port. I’m talking about a server that needs to have ssh available. And I would argue while all the options you bring up are good suggestions; 1) they aren’t alternatives to having ssh on a non standard port, they are additional methods and 2) they will do nothing against system level exploits. If you leave ssh on a standard port, when (not if) an exploit is released you are in a race to patch your system and at a disadvantage. And for what? Other services are on standard ports for good reasons. There’s not a lot of good reasons to leave ssh on 22. Mostly just laziness.
