    I like the concept of a game on pure SQL as implemented here: https://mystery.knightlab.com
    It offers gamification of learning SQL and includes an optional tutorial-like introduction.
    If you already know SQL but feel a little rusty, then this is fun to brush up.
    For beginners it is an easy hand-help first contact.

    The data are artificial and have a slightly steep drop-off when leaving the immediate game track, but I think it still matchs your requirement to be "meaningful". (And if you go intentionally off-track, then there are hints that some easter-eggs can be found, in the shape of jokes. I did not yet manage to get the query right to actually read them... So I think that even beyond the obvious game there is something for the more experienced to hunt for.)
