Bonfire has groups on their roadmap but doesn't currently implement them (although Circles let you do some group-like things). A broadly-available approximation to private Facebook groups would be a huge plus for fedi. Here's a distillation of some requirements-gathering work I did early last year.

Something to replace "buy nothing" Facebook groups
Discussions with people in my neighborhood (without Nextdoor's racism)
Discussions that aren't public for the whole world to see
