In a very similar situation to you 4 years ago and we eventually just went with a community Facebook page because it’s what most people are already on and use. I hate it. Not a good answer but even discord was too niche. Only 59 homes in my community though. You may have more luck with larger groups.

Also, community building has mostly been a flop. That stuff is hard.

Have you seen Barbarian? I think it’ll make the exception list.
