Giving this a bump.

General project update: I've been hit with some delays recently, so I'm still in the process of insulating the exterior walls such that they'll pass inspection with the City of Seattle. I'm hoping to have that wrapped up this weekend or over the course of the following week.

Would I be able to move back to a two leaf ceiling if, after I pass inspection and am done with the city, I pull out the newly installed insulation, block and air seal all of the existing vents and then reinsulate using a "no air flow/warm roof" method?

I would not do that, no. It's not worth the hassle. Just build it as a 3-leaf roof, while taking the necessary precautions.

in your estimation, will I be able to achieve my desired level of isolation or better despite the three leaf ceiling?

Yep! you sure can. As long as it is built decently, it will work fine.

I assumed as much, but wanted to get your opinion before I started putting up the "middle" leaf.

I've been doing all of the work, and plan to continue doing so (minus the electrical, vacuum test, line purging and charging of the mini split system, and sound door install). Since I'm doing the work I can take my time, do it right, and not worry about cost overruns due to extended timelines.

Thanks again Stuart!
