Yes, but most importantly I need to manage my children’s devices; it cannot be opt in and it mustn’t be possible to disable without me approving. Screen time is too easy for kids to work around as is. I also need in-app content type filtering (eg. no shorts, no music videos on music streaming apps) and literally no one is providing such options, not to mention it should be managed in screen time, too. Parental controls are a complete shit show in iOS and the app ecosystem.
You will always be able to come up with some unique combination of features you want from software that it doesn't have yet. Note that none of these social media bans would block Gemini, and most of them don't consider YouTube to be social media. You are still far ahead with Family Link, and Android is flexible enough that if there's actually real demand for these things you can implement solutions and sell them to other parents.
