I haven't actually tried it, but you can use SSM in your ssh config as a ProxyCommand. As I understand it, that will allow you to just use the ssh command as normal, with all the normal ssh abilities to do tunneling and port forwarding.

Yes that's right. You can use SSM to port forward. Here's an example of the SSH configuration.

host i-* mi-*

    ProxyCommand sh -c "aws ssm start-session --target %h --document-name AWS-StartSSHSession"
