What does your social life look like? Because the reality for me is that in any major city, a significant number of places - even if they technically have websites - post all of their events and happenings on Instagram/FB.
Sure, I can talk to my close friends on any number of IM platforms, but if I want to get out and have new experiences, join club meetups, be notified of events at venues I care about, etc. - it's Meta or miss out.
Go to clubs and check the events from ra.co. Go to concerts and art galleries they all have web pages.

Maybe I'm just too old for the kinds of activities you're looking to get into, but I haven't had a Facebook since 2014, and had an IG account for just a month or two during the pandemic, and I've had zero qualms finding out information about what I wanted to do or see.
It's definitely not the size of the city that matters, as I was in NYC and only recently relocated to a smaller (but still major) city.
If all you need is to view the restaurant/event, imginn.com or kittygr.am works well enough for me. I also like libredirect because it blocks the network connections and is convenient, shame that it's a browser extension it could really be built into the browser or something.
Yeah the instagram posting is such a complete BS. I have a bogus instagram account where I don't follow anyone for the couple times a year I need to find set times for an artist or that kind of stuff.
We need to shame artists/events/clubs that only post on Instagram
The first thing I did when I quit social media was sign up for the newsletter of every concert venue in town. I never overlooked a show.
I can’t speak to your interests or city, but as a rule, the greatest trick the social apps ever pulled was convincing the world that they are the only way to receive information.
