Do Snapchat, Whatsapp, whatever else have scheduling features? I have friends that use FB to schedule events and send invites out. And various groups I'm in use the scheduling feature to set event times, etc.
One group I'm in, entirely devoted to online games, has switched to Discord. But there is a 0% chance Discord will be adopted by the rest of the groups/friends that use FB event scheduling and messaging.
Most of my friends group primarily uses Discord these days. It isn't a full throated replacement for Facebook b/c the server isn't full of anonymous randos, but I don't think most of us want that anyways.
Whatsapp for group communication with friends overseas.
Both of these apps don't have the BS that comes with Facebook.
If you still want to get your fix, TikTok is better platform for getting a mix of interesting content from normal people.
Aside from using Facebook messenger to chat, I don't see a good purpose for Facebook any more, maybe the groups are useful for people?
