My soffits are rather large (11" tall by 30" wide) all around the room (16' x 22'). It will take a lot of insulation to fill them completely. Will I get the same effect if I just put a single layer of R-30 or R-38 in them rather than filling them completely?

R30 should be approx 11" already so basically 2 pcs side by side should do it. No need to pack it in tight.

With R-30 being 9 1/2" thick you will be fine putting that in there. I spray foam all our builds and use THX certified drywall costly but works great.
