Given your concerns I'd say media over west Chester.

If you're working in center city, the media/Wawa line runs right through town, meaning you do not have to drive into the city for your commute. At worst it's a walk or a very short drive to the station.

Media itself isn't super diverse, but SOUTH media (which confusingly is part of adjacent Nether Providence) is.

I've lived here for about ten years now, no issues with it and I'm in the exact same boat you are.

Good luck
