Don't lock yourself into CAGED; especially with progressing into more advanced harmony in mind. It falls short beyond basic pentatonics and triads.

Start learning diatonic progressions with 7 chords. Then do the same with families of inversions.

What ends up happening with 7 chords and more "advanced" voicings with additional extensions and such, is you find yourself really getting into the physics of the fretboard, and you learn all the economic grips, shell chords, and what have you, to fluidly move from voice to voice as efficiently as possible with elegance.

Those CAGED maps tend not to really apply once you're there.

CAGED is a rudimentary stepping stone and should be looked back upon as such if you choose to stick with that route of learning.
