Are faculty hiring committees overly polite on "denial" answers
This sounds like a standard US rejection - they may be sending this exact same text to all other candidates that were rejected. I do not believe you can learn anything from it and it does not reflect on you specifically in any way.

You can, however, try to get feedback, but it can be quite difficult - you must realize that the chances of getting good sincere feedback are not high. It is probably best to try getting this from someone with whom you felt there was a good connection or that this person was relatively open. Probably this person would prefer to do this over phone rather than by mail. You may also want to look at this question.
