I’m a fan of just learning as you go. It sounds like you’ve built relatively simple apps so maybe try to build something more complex, even if a “stupid” idea.
Try React or Vue with some database component and go from there.
And before you start, look up a resource for how to write good tests with the tech you choose, and work on that as you go as well.
