It’s a bit larger than the size you are looking for, but the University of Delaware is worth looking at. It is highly ranked and situated in a college town that has an incredible sense of community. There’s a very high number of Jewish students there, so you would surely meet individuals whose religious beliefs align with your own.
As for schools that are a bit closer to you, you should look into Texas Christian University. TCU is within the size that you are looking for and they give a generous amount of aid for highly qualified students like yourself. https://admissions.tcu.edu/afford/scholarship-aid/index.php
Don’t let the name fool you — it is not religious affiliated anymore, and even have Jewish organizations on campus such as Hillel! You would, without a doubt, meet other Jewish students.
Good luck!
