Go for silver if you aren't sure about the common white. I would suggest you to choose lighter colors. Since the car is pretty big and washing it is hard work. After washing, waxing might as well be taking as your weekly exercise.
Stick to light colors. You can be care free and will have peace of mind. Cars with lighter colors sell better too, since faults and imperfections are easily visible in darker colors.
Super white and Silver.
Rest is your choice, brother. If you have a driver then black is fine.
I have a 2015 Corolla, Gli, manual, black.
