When I worked in Men's Accessories at a major department store (selling everything in men's apparel that wasn't a suit or shoes), I learned there are three basic knots for ties. The Windsor is for the spread collar shirt, as it is a large, squarish knot. The Half-Windsor is for button-down collars, as it is smaller than the Windsor, but - being triangular - will fill the space. The four-in-hand is meant for point-collared shirts, being a relatively narrow, roundish knot.

Which shirt to wear with which outfit was not covered - that's up to the wearer.
