Congrats on receiving Fulbright! Anyways, for an international student, I think a key factor in making the choice lies in whether the university is recognized in your home country. I understand that, given your example, Penn State has a quite good QS ranking, while Georgetown has a distinguished reputation for academic and professional development in policy studies. In this case, you may take into account your career pathways beyond grad school to choose between good state schools and top private schools.
