How can I do basic unplug?

What is the most effective thing I could do in 1 hour to minimize my data and AI tracking on my online existence?

Specifically, I dislike how my feeds are curated by AI to maximize how sucked in I get. I just downloaded instagram for the first time ever on my phone and all the suggested posts are EXACTLY curated to my location and interests.
Recommendations for best alternative social media sites?

Can someone point me in the right direction? Thanks.

Edit: I think I wasn’t clear enough. I already do stuff in person with my local community. I specifically want some social media to get instagram-style insights into my friends lives (who don’t live local) without the algorithms and information tracking
