Say I'm convinced that IDs could possibly leak information, but UUIDs are problematic (e.g. cost of enforcing uniqueness grows with each added row). Would encrypting the ID with some symmetric key plus a salt be sufficient? The client sees a number where the ID can be recovered on the server side, but which the benefits of having an easily generatable unique identifier while making it challenging to recover the actual ID).
