All good advice and clearly you way up all the factors. A recent example I had was the tower giving wind just in limits, shortish runway, checked distance required was ok and then experienced increasing tailwind to nearly double what the tower was saying at 50 feet. Maybe it changed at the last minute, maybe they just wanted to delay changing the runway. It does not really matter. It was obviously way out of limits and with no obvious good reason to push our luck I carried out a missed approach. There is no one size fits all, you exercise your best judgement.
