If you are concerned enough about winter driving, your answer is you need winter tires. FWD mini vans with winter tires are good snow vehicles.
AWD with winter tires is better but there are extra maintenance, repair, and higher fuel costs to consider. You pay a lot for the benefits of AWD over the life of the vehicle. AWD could be necessary if you live on a poorly plowed road that is steep, have a steep driveway, or you need to go out in blizzard like conditions to work (ie nurse, doctor, or EMT).
From your description of your driving pattern, FWD with winter tires is best balance of safety and costs for you.
