Great description - so to summarize - in cruise, the CS prop would
only benefit over a fixed pitch in cases where the fixed pitch prop is
redlined before running out of throttle.

Yes, but also the other way around too. Climb real high with a fixed
pitch so even when you're at full throttle you can only get say 2100 rpm
in your 172. In my 182 I can always get the full max continuous 2450
rpm, regardless of what the manifold pressure may be.
