I use the outermost sets of holes like in your red drawing because I love a good wide stance.
Next up is foot direction. I keep my front foot almost perpendicular to the way the board rolls (neutral) so I use the mbs foot strap holes in the alignment like this
Rear foot likes to go a bit forward (posi) with speed so I angle that one a bit in that favor like this
So my overall stance is like this in the end
I keep my rear binding looser than my front by one click because I pivot that one around more than the front. Both feet can still step out of the toe straps though when riding. I mostly just use them to grab with the top of my feet on heel side turns.
