CAGED is essentially an easier way to think of the pentatonic scale shapes, plus a few other tricks for chords. You get pentatonic shapes, Major & Minor chord shapes, and Major & Minor arpeggio shapes. The letters of CAGED mostly match up with the major chord in that specific pentatonic shape. So, the basic minor pentatonic shape will have the open G Major chord shape as its major chord. The trick for finding/knowing what minor chords go with each shape is also in the CAGED name. So, if the G shape is the minor pentatonic, the note after the name of the shape is the root of the minor pentatonic shape: E minor pentatonic/open E Minor chord shape/G Major chord shape...all in the same pentatonic shape. And it continues for the rest of the shapes. The arpeggios are essentially the Major/Minor chords, just individually picked. Love the CAGED system.
