I'd suggest you work it up first and worry about the word limit later. You can always trim things out, you can express things more economically (a good discipline in itself) and cut out waste.
If you really are pressed for space, you can resort almost to bullet points - remember that the people reading these things have got to read hundreds of them, and so it's really about ramming home the necessary information to them as economically and digestibly as possible.
"Depth and breadth" stuff is important, but so is the public speaking stuff. I suggest you get it all in there and I can work with you to edit it down.
