Problem with one size fits all is generally that one size fits poorly most. I have a Drolet Savanah that is 83% efficient. (Incidentally iI see it is on sale must be because of the middle of Winter is near the end of heating season) http://www.northerntool.com/shop/tools/product_200307393_200307393
It meets many of your requirements but it is not a great stove to cook on though I have and do some cooking with it. The reason it is not great for cooking is it does not get hot enough to do much more than boil water.
However when you go less efficient to get more heat you are going to pay for that in terms of amount of wood you burn and how often you need to refill.
At any rate I have had my Drolet for 4 Winters now and it is quite adequate for my small place and my location. If you live in a especially cold area I am not sure it would be able to keep up. That is my experience with a particular wood stove.
