Dinghy can drive you dinghy
Give some thought to how often you will use a dinghy. I have an inflatable with a 4 hp outboard. It has a hard floor, it is very nice for going ashore when we visit barrier islands. I usually tow it behind our Hunter 340. But to be sure, the dinghy is a pain. It doesn't really fit well anywhere, it is hard to lift if it gets water in it and it is always in the way at the marina. I can't leave it in the water because of barnacle build up, and it's too bulky to stowe aboard easily. I could install davits, but that would ruin the swim platform on my boat which is one of its nicest features. So I would ask you, do you really want a dinghy? I have used mine once, and I just brought it for the kids. They enjoyed it, but it is a lot of trouble.
