I run ssh/mosh on a Linux laptop to my Mac desktop all day every day. I suspend the laptop every night, and when I open it in the morning, it immediately reconnects.

I run tmux (locally, nesting another session on the Mac) but I don't think that would make a difference here.

I'm not aware of any special config, but I've been using this setup for several years with no major adjustments.

I wonder if there's an issue with my firewall (little snitch). I'll try disabling that and see if that helps any.

Sounds plausible. You definitely need UDP ports 6000-6010 (?) open incoming to the Mac.

I ended up deleting a few extra rules I found in little snitch, and things seem to be working much better. I guess maybe there was some contention in the multiple rules.
