Most beginner's roux examples use Sune (once or twice as needed) to orient the corners (which doesn't permute them), then do J perm (13 turns) twice or Y perm (17 turns) to permute corners. If corners are permuted first, a 9 turn sequence where only the 5th turn varies can be used to swap front 2 corners, back 2 corners or front+back 2 corners (diagonal swap with U or U' done first). This order makes sense if doing layers, but with Roux, the last 6 edges are handled last, so for beginner Roux, it seems that permuting corners first is simpler. To simplify looking for corner permutation, I look for adjacent orange or green corners put them at the front top. If orange on front top, green should be on left, if green on front top, red should be on left.

swap front - L' U' L F U F' L' U L

swap rear - L' U' L F U' F' L' U L

swap front+rear - L' U' L F U2 F' L' U L

diagonal - U then swap front+rear

Sune sequence doesn't permute corners, although you often have to do it twice. I do Sune in reverse order so that one hand does L or R turns, the other U turns:

L U2 L' U L U L`

R U2 R' U' R U' R'

For reverse order Sune, the starting position needs to be adjusted. View from the top, start at the +. If only 2 yellow corners facing up, start with yellow facing out on back side. If 0 corners facing up, start with side with single corner facing out (or any headlight if pair of headlights).
