Firm on the aim point is always better than a floater, X-wind or no X-wind.
Any intervention should happen well before the outer marker. If the a/c is set up properly then keep your hands off ( and your trap shut) unless you see things getting dangerous at which point it is a go around.
Where things go wrong these days is that people get used to 12,000 ft of bitumen and forget Rule One. Then one day they get a short runway a la 16L/34R at Narita (2,180m) and end up in the grass.
