Does WordPress provide different levels of logging?

Your understand is correct. WordPress doesn’t have levels beyond Warning and Error from PHP.

Wonolog, a WordPress wrapper for Monolog, expands the default error logging into the levels you require. You can also expand the logging by adding your own custom debuging alerts and level.
