Yikes, not too many options for an 85mm f1.2. I started down this path thinking 35mm for full-body shots at 10', with a background at 5' behind the subject. And then the question became one of whether the 35mm f1.2 would be necessary, or perhaps the 18-35mm 1.8. I might have to settle for f1.2 (settle?) and have a non-descript background slightly out of focus.

Still, all good information. Thanks for the help! For now, I'll keep to the outdoors with my 70-200mm. That gives me a lot more room to stage a portrait.

And a million good photographs have been taken with that configuration. You will have to plan and choose your background rather than going for "certain obliteration" with the lens, that's all.

Here is another example of a partially obliterated background which will hopefully give you a better sense of your options. This is from an extremely low-light wedding where I was using the 70 - 200 at f/2.8.

My focus point is on the B & G, and the lens is extended to 200mm. At that shallow DOF the deep background has been obliterated into an OOF abstract. The priest is totally unsharp but focused enough to add to the sense of context. Aesthetically your eye is first drawn to the bride, her bouquet and then the groom, all of which are in the sharpest focus.

IMO, full-body shots are often overrated. When you're forced to work in a constrained space, 3/4 shots are way easier to pull off, and almost always just as interesting.

I'd rather have a top-notch 3/4 shot than a full-length shot that was forced and imperfect due to space and set constraints.

I understand and appreciate your point, and I've used the technique in order to preserve the context while also putting the emphasis where i want, but that's not my goal right now.

Edit: I've tried to do so well in the past, but that photo is terrific!

I think you've hit the nail on the head there.
