afaik Friendica is the closest to Facebook usage among Fediverse platforms, im not aware of new features on Facebook since I quit it a few years ago but for ordinary people i only think to be missing games i know some people used (do they still?) to play to get “achievements” which they could share they got it, i’d usually see it more often from farming or guitar hero-like games, other than that they have plenty of stuff that you won’t find in other Fediverse platforms but its also not a platform where you’ll find general instances with as many people as in Lemmy/Mastodon/Pixelfed general instances but since you are willing to host for yourself and your friends it might be worth it, you can even have your own RSS feeds within Friendica and browse posts from other platforms outside the Fediverse, you can check the features list on friendi.ca/about/features
