A lot of good information here Dan!
I just wanted to mention that a real omni mic really is required.
A switched mic is nothing more than two cardiod mics (a velocity type of mic even if it's switched) and they will have a different diffuse field response than a real omni mic (works on pressure principle). A real omni mic can be had for $50 (Behringer ECM8000). Like you say the response linearity isn't really that critical for room acoustics measurements and noise floor isn't really critical either unless you want to do critical noise measurements but the real benefit with the real omnis is the small body, smaller diaphragm with minimal intereference as well as a much better bass response.
Best,
