Case Western Reserve offers a joint music program with the Cleveland Institute of Music https://music.case.edu/about/joint-program-with-cim/ and comes in just under your maximum driving radius (half an hour closer than Oberlin). Within your radius southward, U of Richmond is worth a look - there are music-specific merit scholarships - recipients need not be music majors but I believe they are required to do the minor.
Schools potentially worth looking beyond that radius for: St. Olaf in MN and Lawrence U in WI. St. Olaf is particularly strong in Math/CS as well as sciences, and Lawrence is especially strong in physics. Music pervades the culture at both schools and opportunities for non-majors are excellent.
On the reachier end, JHU/Peabody has a strong jazz studies program if that is his focus.
