I adjust the wall by length instead of grabbing the endpoint and dragging it to the other wall.
Find the length of wall needed to fit the space, without snapping to an intersection, then select the wall to adjust and then click on it’s displayed length and change it to the length needed.
Optionally…set your ‘Nudge’ to a 1/16″ and ‘bump the wall into place against the opposing wall, without snapping to intersection…then drag the other end to where you need it.
