I like sqlbolt a lot. Codecademy's SQL tutorial is free, but maybe at this phase it makes sense to step away from super hand-holding tutorials/resources.
I agree, if someone has made it this far I think they're ready for more self-guided learning
https://sqlbolt.com/ is a great online tutorial for learning SQL
https://www.postgresqltutorial.com/ is specifically for PG
https://university.mongodb.com/ teaches Mongo, requires signup, but skills are transferable to other document stores.
