No longer a teen, but I remember liking the information laid out by https://www.bls.gov/ooh/

It broke down stats around career prospects, the education requirements to get into that career, the outlook of future job prospects in that career, etc. I didn't really care too much about what job I worked, just that I had one, and then I could at least enjoy my life outside of it comfortably. I found a few that seemed interesting to me and worked to those. I think having it all laid out for them would be helpful for them to make their own informed decisions.
