Second, the cross type sensors are in the form of a large X not a +.

Wrong, that is only true for the center f/2.8 and better AF point on the 7D, the rest of the AF points is oriented like a +!

I thought that the center pt. on the 7D was both X and + orientation?

OK, now I'm sure of it:

Quote:  ​The actual AF system in the EOS 7D is entirely new to the Canon line, with an AF sensor having 19 cross-type AF points. Each and every point, including those located farthest from the center, is a standard-precision cross-type sensor, which can be used with any lens (or lens plus extender combination) with effective maximum apertures of f/5.6 or faster. Like the EOS 60D and 50D before that, the center AF point also has a separate, diagonal pair of high-precision line sensors, which provide even greater precision; these are automatically used with lenses f/2.8 or faster.

End quote.

When you get down to the nuts and bolts of photography, the results depend on the 'nut' behind the camera!
