Most of the theory you need is baked into the courses. Beginners should mostly focus on physical playing skills. Otherwise, you know musical ideas but have no way to put them into practice.
If you want more in depth on theory as a beginner, my old GF2 course is a great place to start. It starts with intervals, then scales & chords.

These next tutorials are a little more complex, but here for your reference.
This tutorial covers the basics of chord theory.

This one covers harmonization of the major scale into the chords that make a key signature.

But remember to focus on your playing skills. You knowledge about theory should grow with, keep pace with, your playing skills.
Please ask more as necessary & best of success! Hope that helps!
Hey! Super cool of you to jump in here and reply to my questions/concerns and offer some helpful advice. I need to understand the behind the scenes stuff so all the stuff I'm doing in the other course work clicks a little more solidly, otherwise all I'm doing is playing what I'm being told to play, but not understanding truly why. I'll give your old course a shot and see if that helps me put things in place a bit more. I want to be all that I can be with this stuff :)
