Now if your Screen wall is at least 9' tall, and there will be only one row of seating, then you could roll with a 170" @ 83"x 148" and that would give you a 161" 2.39:1 screen (62" x 148")
Another important consideration is the construction of the Frame. Even the 16:9 format will require a sectional frame because Clear Poplar lumber usually doesn't come in lengths longer than 10' (120"). But no worries there is that is your decision because I have the plans you'll need to make that happen.
The diagram below gets you close enough at 165" diagonal......

And should you need instead consider a screen that isn't 7'+ tall, below is a 170" 2.39:1

The Frame above uses a different sectional design, but can just as well be done using the same design as the 16:9'er (...the design was for Spandex but of course is also applicable for Flexi-White...)
So OK......170" viewed from 12' will be a ginormous experience, and certainly call for a ultra smooth surface. I would however suggest that the Screen be built in 2.39:1 format at 66" x 157" and you go with a Constant Image Height layout that would still allow you a 135" diag. 16:9 @ 66" x 118". I have found that those I build / paint screens for appreciate having a epic-ally wide image more than they do one that strains their necks. And your 12' viewing distance will do that.

I would say keep that inclination.
You could do that...but you might also consider driving over to Austin next Sunday or Monday, because I'll be there painting a Screen Wall (lBack Flame) and installing a massive 9.4.4 KEF Theater system as well as 24 Ceiling Speakers (12 rooms) You could get some "Hands On" teaching experience on how best to HVLP Spray a large area
That too is another choice (N/C version) however at the quantity you'll need it and the supplies you'll require to mix it up it won't be much less than the pre-made BF, and not quite as high performance.
You could do that as well, but be advised the difference in white / black contrast and the loss of color dynamics (saturation and brilliance) will be considerable. All it would be is simpler. Even the Ben'es brright output won't compensate for the lack of reflectivity off the Flexi-Grey
Nothing worthy of note....and any that do claim to be advanced Paints with "high contrast - high performance" cost a lot more than is sensible. Sadly, it's a Seller's market out there in as much as the buyers are essentially clueless...and gullible.
Your absolutely welcome. A project such as yours deserves a careful approach, and asking questions first is the best route to a successful outcome
