I am no expert, I just said what worked for me in the past. I ssh into
many systems everyday so changing to non-standard ports is
inconvenient. Rather than speculate what other ways might work I chose
to suggest what has worked for me in the past.
In any case I don't think many ISPs forward all ports to the user.
Depending on their policy, they will forward certain ports. If its a
non-standard port, and the ISP forwards selective ports it is more
likely that those will be blocked.
In any case I think Ed's suggestion is something the OP should try too.
Open source is the future. It sets us free.
