Sure just like movies, video games, fine dining, skydiving…
They might provide you some kind of mental entertainment, but certainly don’t tangibly benefit you (the nourishment of fine dining not withstanding).

It's been exceptionally terrible at this for a long, long time now. For instance - had a friend I hadn't talked to in a while (as happens as you grow older, sometimes you only talk to people every 1-2 years but remain friendly) died recently. It popped up in my feed, somewhat as a shock to me - he had had cancer for the last year. Now, it's definitely on me for not keeping in contact more frequently, but I was shocked at how many updates about it I saw on his page that never once made it to my feed. Facebook didn't think a guy I'd been friends with on the platform for a decade and had 200+ mutual connections was anything I'd be interested in. It's explicitly anti-social by design.
As for the other things in your list, I've never found any value to any of that but I acknowledge some might. I also don't think you need a platform like FB/IG to do either of those things and the only value they provide is the network effect.
Instagram provides a high latency poor resolution picture and short video service with comments, which you can get from anyone and everyone on today's web.
