My impression is W&M is in many ways functionally a DC area school. Lots of alums, lots of people do internships, lots of recruiting, and so on. Of course they also go all over the country, but I would not worry about W&M lacking those sort of concentrated opportunities.
In terms of law school, I would first urge you to keep an open mind about whether it is really something you want to do, and ideally work for at least a couple years before deciding.
But in terms of admission, among colleges like this the best bet is the place you think you will be happiest because that is also your best bet to get the best grades.
So basically, in my view this is not a matter of choosing either at which school you think you will be happiest, or instead choosing the school which will give you the best prospects for next steps in education/career. With a comparison like this, it is actually the same question, because how you actually do in college will dominate that second question, and the first question is a major factor in how you actually do.
