About GPS measuring Ground Speed and ECEF Position at high velocity, I really do not know about how the accuracy is affected, Doppler effect, etc.
It's not physics, it's firmware. Limits are result of treaties.
See section 11. But it seems that you need an expensive GPS module.
The firmware/hardware isn't more expensive, only the paperwork. You have to prove you won't pass it on, among other things.

I don't know, sorry (don't see why not though, try it in
simulation...). Maybe someone else can comment on that.
Do I understand you correctly:
* the rocket will go directly where you aimed it, it's not actively "navigated'
* the autopilot is not responsible for maintaining vertical attitude
* your instruments require a constant orientation (roll in the
rocket's frame of reference) during the preiod between boost and apex.
* your experiments require position and attitude logging during the
same flight phase.
