My 13 mile commute is largely non-stop with few junctions, most of which don't require a stop. I've only ever ridden a road bike and don't have a Dutch bike. I do have a mountain bike, but with fat, treaded tires so I wouldn't even try to commute on it.
Weather, route type / terrain, and personal preference definitely influence the type of bike will work best for you. I like to travel light and I feel my commute allows for this. I only have a seat post mounted trunk rack, no fenders and only one sufficient head light and tail light.
