If you truly are never going to drive in snow or mud then 4wd is useless. With 4wd everything is more expensive - balljoints, bushings, extra transfer case and drivetrain parts to deal with, etc etc etc.
Also many 4wd 'beater trucks' are truly beat to hell and back. I went through this and ultimately discovered that I'd have to pay +20% to get 4wd but +40% to get 4wd in decent condition that wasn't a work truck and that just wasn't worth it to me.
I ended up with 2wd, and I still drive the thing in snow (granted I live in the southeast so we have a different definition down here) and had no issues with a set of chains combined with a mediocrity of intelligence. That being said, in any sort of real snow situation 2wd is a joke compared to anything with 4wd. Basically you're right, that awd pacifica will do better than most 2wd trucks. You're probably not going to go camping in snow/ice so it sounds like that hill won't be an issue.
It might be worth looking into what the pacifica can safely tow. I doubt it's much, but it would probably be ok with a popup camper.
All of this being said, you live in PA. If I were in your shoes I would probably invest (careful word choice) in a decent 4wd 4 door truck or SUV that I'd have for a long, long time and then you wouldn't have to worry about 4wd when you sell the pacifica.
