For strong supply chain management in the south, yes, U of Tennessee Knoxville. If southwest also works, look at Arizona State too. Both are campuses with plenty of fun available!
One thing that can be tough for introverts is putting themselves out there to get internships and work experience. If that’s you, a school with a co-op program might be a good choice. U of Cincinnati pioneered this approach, and their business school “offers an innovative approach to business education that we call PACE. The PACE framework allows students to create a customized roadmap for developing proficiency in Professionalism, Academics, Character and Engagement to ensure they can successfully pursue the personal and professional goals they are passionate about.” They have a co-op based Operations Management program, which includes Supply Chain content but is a little broader. https://business.uc.edu/programs-degrees/undergraduate/majors/bba-operations-management.html Their First Year Experience includes small-group Learning Communities that are good for building social connections.

Coming from a Catholic high school, would you also like a Catholic college? U of Dayton could work Operations and Supply Chain Management (Bachelor's) : University of Dayton, Ohio especially if you’d like a mid-sized school (about 8000 undergrads) rather than a large public. Closer to home, Marquette (7500 undergrads) could also be a good fit Operations & Supply Chain Management Major // Undergraduate Admissions // Marquette University Maybe Loyola New Orleans, although their Business School doesn’t have an operations/supply-chain specialization for undergrads; great social environment, though!
What are your extracurricular interests? Sometimes this can be a good way to narrow down - look at campuses that are particularly strong in a non-major activity where you’d find your people, whether that’s a marching band, or an outdoor recreation club, or a great club team in your sport, or whatever.
