If you wanted to actually empower parents in helping their kids, you'd make sites emit some form of standard as TXT, SRV, /.well-known, whatever end points
Then you'd make sure that the owner of the device has the ability to enable this, factoring in some tags for the category
us-min-age:21:drinking
gb-min-age:18:drinking
au-min-age:16:socialmedia
us-min-age:13:socialmedia
Then I can use my existing parental controls (including on a linux laptop if I don't give my 13 year old root) to apply or not apply rules
If I don't want social media regardless, then I apply a rule "no scoial media". Or I can apply "1 hour max" per day for the category
If I'm happy with my 16 year old spending half an hour on playboy.com or whatever, then that's fine too -- I'd rather they went somewhere like that then some of the shadier sites
This gives no power to large companies, but helps the parents, who can apply "default" profiles -- hell you can distribute default profiles as part of the onboarding process.
