7D is a more versatile body than the other 2 bodies... Better focusing, micro adjustment, quicker response, etc...

Depends on what type of photography you are shooting. For still non-moving target, results should be the same or super close; whereas, for moving target,  the results can vary by quite a bit...

Heavy body is more ideal if you are pairing with a heavier lens. The center of gravity is more balance at your wrist. Light body with heavier lens can hurt your wrist easily.

Yes and no, depends on how many upgrades you are proposing in the future...

The other concern is people are likely to have many EF-S (or other cropped) lens in their gear. It stops people (for amateur purpose) from moving into full frame.

In your example, people using crop bodies tend to pair with the Sigma 30mm f1.4 instead of the 35mm F1.4L. The result is just so close for output...

In my opinion, short to medium range zoom lens made by Canon is performing so bad (compared to the price tag). There are so many lemons for the L series. Surprisingly in my experience, the best zoom lens I can recommend in the Canon lineup is the 17-55mm F2.8IS. You won't even get a "level" upgrade even if you are using 5D2/16-35f2.8II or 24-70 f2.8 combo.

Last week I picked up a Zeiss ZE 21mm f2.8. It's the best wide angle lens (I would call it a beast) I've seen so far, result is just amazing and pleasing...

17-55mm f2.8IS worth that price in terms of the photo output and workability...
