I'm not convinced this is the correct move, if only because anything short of draconian control is going to be lossy, and draconian control has catastrophic failure modes for people who are naive to the things you're trying to help them not be overwhelmed by (see: abstinence-only sex ed).

There's no one-size-fits-all pitch, but my starting point would probably be time limits per day on a smart device, killing all notifications on it, and telling them that these things are because it has bad consequences if they don't have limits, so if you catch them getting around the limits, the privileges of such things will be temporarily or permanently removed.

I don't love it, but unless someone comes up with a wonder drug to dampen addictive effects of things in humans and we're all somehow convinced this is a great idea to give to everyone, all you can do is avoid the parts that are a race to the bottom of gamified attention and focus, until they're old enough that they hopefully have an informed opinion and are the ones making the choice to drink the poison chalice or not.
