Seems all the different light systems really don't work together. I found you basically have to turn the sun way down to just see any photometrics and/or standard light.
try camera for exterior = f-number 4, sutter speed 100, film speed 100
camera for interior = f-number 4, sutter speed 100, film speed 400
sun way down to 0.1
sky way down to 0.08
first bounce at 3, second bounce at 1 or 0.85
