Is there any physical advantage of using 12/2 or 12/3 when meeting 404.2 C requirements?

Yes. If the circuit (or branch thereof) is not supplied through the switch box, you'd need (at least) 3 conductors?hot, switch leg, and neutral?run to the switch box.

Agreed... I was just wondering if there was any wiring advantage to either switch first or box first as far as conductor fill or cable runs.

If fed from below, run through switch box.
If fed from above, hit light box first, then 3C to switch box.

To be honest, I don't really understand your question.
At the risk of learning something
Why would you need a neutral in a switch box if it were fed from the light? All you need is power and switchleg/s. And a ground.
If it were fed through the switch box a neutral is going to be passed through. Which is the way I do it.
402.2(C) to help you get on the same page.

It's 404.2(C)
Also, unless you're on the 2011 or 2014, that section doesn't apply.
Some people use either 12-2-2 or 12-4 when pulling for a 3-way switch. But here it is not stocked and would have to be ordered.
To be honest, I don't really understand your question. If you pull 12-2. you would have to pull two cables to comply. 12-3 would meet the needs of the extra conductor for the switch box requirements. This of course is just for a SP switch. If a 3-way, you would have to do something like I mentioned in the first paragraph. And all of this also depends on whether you can/can't use either of the exceptions.
As far as I know California Travelers are only standard practice in California. There are a few Californicators that try to bring this style of wiring into my state; they are dealt with on a case by case basis.For the most part we need to quit using the hot at both ends method.
