I'm assuming since all 3 lights have the same emitter, how would the beam pattern differ in these lights? Is a wide, shallow cup made for flood and a narrower, deep cup built for throw? Is orange peel made for flood and smooth made for throw?

The bigger one should have a little bit better throw than the other one.
And I have one question: imagine that these two reflectors have the same max. diameter and the same depth. The only difference is the smaller diameter, around the led. So, which will be the difference in throw or beam pattern?
If you imagine a flexible reflector in your mind, shorten the reflector while keeping the width the same (move the LED forward), and you'd logically have wider spill. Move the LED back, and less-wide spill, but only to a point (effect diminishes).
Now instead, widen and narrow the reflector in your mind. Wider reflector, I would think, produces a wider beam (think a car headlight). Therefore, the opposite--narrowing the reflector--produces a narrower beam.
Therefore, I conclude that a long, narrow reflector produces the tightest hotspot. That said, the closer to a "point source" the emitter is--that is, a small LED--will help with this. The bigger the LED surface area, the less-well this works (or you have to make the reflector a lot bigger in relative dimensions to compensate).
Anyone feel free to prove me wrong here. Full disclosure, I don't have one of those imaginary flexible reflectors. It's just a thought experiment.
I did notice chqualitygoods touting that the Yezl Y6 has a reflector "2.2mm longer" than its competitor, the C8. Note that the reflector is, however, narrower than the C8. I don't know if they're accurate on their claim of "perfect reflection curve", yet with all the puffery of Chinese vendors, I've seen no one else claim such a thing.
It should be easy enough - there is free ray tracing software out there. That will allow you the infinitely flexible reflector. You can get the LED beam profile from Cree's website. I hope it has got better than when I last played with it, it was somewhat less than straightforward a decade or so ago.
One of the guys round here with CAD experience ought to be able to do this. I'm not that guy, I'm afraid.
