Another way to look at this. Knowing what intervals look like on the guitar, will double the speed of learning these mechanics. (I don't know how to use the computer fretboards)
3rds, 4ths, 5ths, 6ths, etc., have the same look, regardless of where you are on the fretboard, e.g., the tritone has a look, 7ths, 6ths, etc. Fretted instruments of any form have this look. All other instruments must be learned by rote, to one degree or the other.

Play G bar chord.
Play the major scale a maj 3 below or m6 above the root of G or 1/2 step above the 5th.
That "is" your Phrygian mode. Or another way to say it, this is the scale that gives you G Phyrgian. Altering that scale, gives you the other variations. You can play an Eb scale or play an Eb scale from G. The sound is Spanish.

A F scale is the dorian scale. If you like, play a F scale from G.

A C scale is mixo for G. A 4th above G.

A D scale is lydian for G. A 5th above G or another way, it is the 5th of G. Play from G or from any note of the chord.
You could play a Bm7 arp using the notes of D maj scale in passing and it would still sound lydian. If you want to play lydian for G, play a D melodic minor or a D major with a flat 3rd from any note, you have your lydian b7#11 sound.(G7 altered)

So on and so forth...

Hope this helps a bit more.
