The answer to your question is yes.
I live in my Excella and, depending on the weather, I do every option you listed. I only leave the roof vents cracked a little when running the AC. With the windows shut, only the hottest air gets to them anyway and, as far as I am concerned, it's welcome to exit the vents.
Right now, the daytime temps are in the mid 80s to low 90s most of the time. When I go to work I leave the Fantastic Vent in the bedroom blowing out on high and crack a window in front. When I get home from work, I shut off the FF, close the window, and turn on the AC. Not necessarily in that order.
It gets comfortable pretty quickly. When it gets warmer, I leave the AC running full-time.
As far as condensation goes, running the AC tends to dehumidify the air making that pretty much of a nonissue. Lately I have been noticing condensation on the windows in the morning, but it's on the outside
You'll figure out what works for you pretty quickly. Enjoy!
