I'm fairly familiar with chords and scales.
Ironically I tend to use pentatonic scales the most. Mixing in all the chromatic and microtonal stuff.
A lot of people look for short cuts. But the only way to really become familiar with this stuff is use it.
I take it you started looking at the modes based on the harmonic and melodic scales.
All these can be used to make chords also.
As you mentioned they have a unique flavor that comes from the scales and chords.
Some being more useful than others. Obviously all subjective taste.
But the only way to become familiar with them takes time.
I did this in the 70's.
