Navigating the ii-V-I (part 1)

OK, let's apply some of this pentatonic stuff.

Here is a very traditional progression
ii-V-I

So in the key of C, that is:
Dm7-G7-Cmaj7

1st option - Play it with one scale

Use the D minor pentatonic

The scale over the ii is D-F-G-A-C (1-b3-4-5-b7)
Over the V is G-A-C-D-F (1-2-4-5-b7)
Over the I is C-D-F-G-A (1-2-4-5-6)

Or A minor pentatonic

Over the ii is D-E-G-A-C (1-2-4-5-b7)
Over the V is G-A-C-D-E (1-2-4-5-6)
Over the I is C-D-E-G-A (1-2-3-5-6)

Or the E minor pentatonic
Over the ii is D-E-G-A-B (1-2-4-5-6)
Over the V is G-A-B-D-E (1-2-3-5-6)
Over the I is D-E-G-A-B (2(9)-3-5-6-7)

In jazz, it is common to play the Dorian mode over the ii, the Mixolydian mode over the V, and the Ionian or Lydian mode over the I. So here are all of the minor pentatonics you can use over this progression.

Dm7
D
E
A

G7
A
D
E

Cmaj7
D
E
A
B (Lydian)
