IMHO FWD vs AWD doesn't really change the tire size considerations other than making it more important that front and rear diameters match (how critical this is depends on the precise workings of the AWD system).

There ya go, buy a set of four tires that are the same size.

And, those 4 the same size should be the same brand.  It's somewhat surprising how much difference there can be in tire brands that claim to even be the same size. 

Driving through deep snow seems to reward a narrower tire.  The narrow seems to cut down into the snow more than a wide tire which tends to float on the top of the snow.  Driving through deep snow also seems to reward a shorter tire which then leaves more wheel well opening.  A taller tire and less wheel well opening really can get clogged with snow build up in the wheel well.  But, not such a small tire as to so greatly affect ride height.  A lowered car in not great in deep snow.
