Hey Chris, my previous reply was marked as spam for some reason so I have included it below.
I guess don't see the reason for the profile to be there at all (other than to let the user that the sketch is closed). Just select the sketch (actual sketch lines or the box in the history) if you want to use it for something. If the sketch line passes over any part of a body entity you are trying to select the long press makes perfect sense.
The issue you have with the sketch being over the face is (most likely) because you're used to the idea of a sketch profile blocking parts of the body. If the profile wasn't there (or at least wasn't masking the body entities) you could have the sketch cover the entire surface and still select the sketch or the face or anything (of course long pressing for options if the sketch line is covering any body entity you wish to select).
No doubt this type of system works in Fusion. I'm just used to a different environment in SolidWorks where the sketch doesn't block anything and it makes things just a bit more streamlined (less clicks, less options to configure to do stuff). The difference is subtle but I notice it immediately when in the sketch environment and I want to measure stuff beneath a sketch.
The screencast below is sketching in SolidWorks. Notice how in the sketch environment I can select and measure without doing anything extra. And the Object-Action workflow is the same. The difference is that Fusion blocks selections with sketch.
