If you like podcasts I really think the Lawfare Podcast (lefties), Advisory Opinions (righties) and Divided Arguments (not sure how they lean, they're more bland, but it's still good, with less frequent releases) are my go-tos for legit, subject-matter expert driven long form legal/court commentary.

TLP has a much wider range than the other two. Their focus is generally in National Security related matters so you'll get stuff about foreign policy, three-letter agencies, what's up with Trump this week, interviews about specific topics, AI, etc.

AO really only talks about current court cases in district courts or supreme court cases. Also have some stuff for advice for legal students periodically, I skip those because I ain't trying to be a dang lawyer, but I just think it's REALLY important to know what's going on in the courts

DA is like, the most boring. But it's great legal review.

Good luck navigating teens on the Internet! Keep hammering home safety, privacy, you can NEVER take back something you post, and that they're only seeing their friend's highlight reels so try not to compare how they feel about their life with what they're seeing on other's posts.
