Womans frame (different propositions from mens) hybrid or mountainbike depending on the wheelsize you want. I suggest no suspension. Let the tyres do that job when needed (fatter tyres low preassure). Swap the stock flat bars for northroad or similar to get a more relaxed (comfy) ridingstyle. I did this to my hybrid (that I did not use before) and to several older MTB`s. Like this solution alot. Also you can go back to flat bars or other type of "agressive style bars" if you want to. If you buy a comfort bike you are stuck with a comfort bike. Not much to do about them.
