Fordham is not considered a national school, at least, it's not anymore national than BU or BC. However, Fordham is still considered a very good school. Not up to the level of Columbia or NYU, but very respected. It also has great placement rates in and around NYC and elswhere in the tri-state area (NY/NJ/CT).
The reason it is considered more regional is because most recruiters at the school are NY firms. I don't think this is a problems since most of the student body choose to remain in the area after graduation anyway. If you wanted to go elsewhere, you may have to do some outside research and set up your own interviews, but you should do well even if you decide to go that route. Fordham may not be national, but going there shouldn't close any doors.
(BTW, I know three people who went to Fordham law in the past few years. All were happy there, and all chose Fordham over higher ranked schools that were not in the New York area. None of them seem to have any regrets.)
