> First off, you want to keep both of the pair’s signals close to each other throughout their length. The closer the two signals are, the better external interference cancellation works, and the less noise they radiate (…)
Wrong! This is a myth that's stubbornly difficult to weed out. The coupling between the wires of a pair is only ~12% the amount of coupling to the reference plane.
On a PCB it's best to treat each signal on its own and route it as a single ended, coplanar waveguide surrounded by reference planes. This allows to use far thicker widths, which reduces inductance, which also reduces the coupling to radiating EM fields.
