I would encourage her to pick up on an activity that you’d be okay with her sharing online - like creative writing or music (as opposed to showing photos/videos of her face/body, which is my guess is your biggest and rightful concern).

The main attraction for “kids these days” from my perspective is a desire to compete (and connect) with one another. In terms of platforms that are about social expression, imo this is best channeled through creative expression on the platforms. You could also encourage her to get a boyfriend and then very quickly she’ll need to learn what she’s okay with sharing while the esteem of a young man she cares about is at stake.

It’s not oppressive to want to protect your daughter. She likely needs some creative competitive/connective outlet. Something that defines her from others while endearing her to others still - something that helps her form an identity. Plus, she might learn a skill that turns into something meaningful - whether as a “job” or just a meaningful reprieve when life gets tough.
