That sounds exactly like the way I use my Trek Verve 1. Probably more like 90% on road/paved trails, but I do take it down an old gravel road and across an earthen dam that has a smooth packed dirt trail on occasion. It could benefit from wider tires off road, but for the little bit I do they'll suffice. The Verve 1 has a rigid fork and rim brakes and its fine for the light offroading I do. I haven't had it out in the rain so I can't really comment on wet stopping power of the rim brakes, but with the rough machined rims on my wheels I expect the brakes would work well enough. At 107 pounds I'd think you could probably get away with the minimum air pressure in your tires and get a softer ride. I'm 230 pounds (and dropping) and ride near the maximum pressure.
