It sounds like you've thought it through and have good reasons for your choice.
One suggestion, from my own experience: make sure that the social scene suits you. I chose a small, liberal arts school in a small town. From Sunday morning until Thursday afternoon, all everyone did was study. No one took a break to see a movie or to hear some live music. It was utterly obsessive, and given the school's setting, frankly, there wasn't much else to do! And then from Thursday afternoon until early Sunday morning, all they did was drink. A lot. Non-stop. I am not a teetotaler, but that just wasn't my social scene.
People at the school seemed very nice on my tour and overnight campus visit, but I wish I had dug a bit deeper and compared what I like to do for fun and how much time I would want to spend studying to the norm for the school. I never felt like I really fit in there.
Just a bit of hindsight from an middle-aged mom...
