Hello, Kenny, and welcome.
What you should work on depends greatly on your goals. You need to have in mind what you want to accomplish and be as specific as possible. In fact, write it down. It makes it more real.
If your goal is to master as many scales as possible (which it sounds like it is), then take a look first at Pebber's videos on the 5-position CAGED system. That's the starter point. It teaches you 5 position shapes you can use to play all major and minor scales. He teaches it in the key of G because it fits easily on the neck and makes it easier to understand, at least that's my experience.
Once you learn the 5 positions of the major scale (and also the minor positions; it's one of the positions), you can learn the harmonic, melodic, and natural minor (which you'll have already learned).
Use the G major scale to start. Once you learn the note intervals through dedicated and focused scale practice, as well as the note positions through theory practice, you can move the scales wherever you like and play anything.
