I'm still trying to assemble a way to put together the pieces to not only return to tmux sessions after detaching, but after detaching and the underlying server reboots. Playing around with CRIU, but trying to make it all automagic with nested PIDs, restore the screens and shell history buffers just how I left them, and implement the common use case of automatically re-establishing ssh connections remains a challenge.

I've never used this myself, but you're describing what a coworker used to recommend when that topic came up many years ago. See the bottom of this page about byobu.

I'm sure there are newer/better? tools someone might recommend here too.
