Do you have a specific area of interest for CS such as Artificial Intelligence, Data science, Software Engineering, Cybersecurity, Game Design?
I would compare the curriculum and available courses to see if one of the campuses has specific areas of interest you would like to pursue with your CS electives.

I agree that academically they will all be comparable. Location and general student vibe will vary between campuses.
Internships/Jobs will be available through the Career centers and your own networking skills. I would check out the Career centers for each school and see which employers actively recruit.
