Look to see what schools are in a 2 hour radius, so you can watch sports events, etc. when you want to. I don’t know anything about Episcopal, other than what I have read here on CC. Lots of people love it. There are several other boarding schools, though, that fit your priorities. George (PA) and St. Andrews (DE) come to mind, and they might be drive-able. For me, it helped knowing that I exhaustively researched options before handing over my kid to anybody. Even if you decide against boarding school – you know what you are saying no to. You have options.
