An all important difference if one is primarily interested in deep
shadow distinctions during editing an image. Assuming a profiled
monitor, not everyone is able to clearly distinguish the compressed
deep tones of GG2.2. Aside from color gammut (not an issue here),
presumeably that's why there are different workspaces. Color
management per se works with any choice you might wish.

Nor worse either.

If you are editing anything visualy you are pretty much matching the
workspace in any event since that is what you see. The issue is what
it is that you see and, as you said, documenting it for the next
managed conversion.

 What matters most is that you've as accurately as possible

And that Is the point of profiling the system in some way.
