I think it's great that you're learning and dedicating time to studying, I must admit that I feel the same as you! For a long time I only used platforms like WhatsApp or Facebook, I even used Instagram for a long time. Today I'm cancelling all those services and focusing my attention on projects like Nostr, SimpleX, Tutamail, among others that are more focused on not collecting data and with better development towards the privacy of their users.
