Is there an equivalent other than remote access?
Yes, there is waypipe. Very close analog to ssh -X, arguably better. Even lets me access my local clipboard in wl-copy/wl-paste commands on the remote.
It's not part of ssh though, so needs to be installed on server and client.
I found waypipe to be way more responsive than X11, and just ... better somehow. More integrated into the other programs.
When using it, take care that pam is enabled in sshd. Else it won't initialize the proper xdg environment which wayland stuff doesn't like.
