I paddle an Alchemy L as my normal boat (I am 6' and 210lbs). Works fine for a lot of things, but not great at many things also. have done up to 2 nights out of it, but you do have to pack lightly.
I would get butt time in all the boats you talk about and see which feels best to you.
On sun, getting some sort of tarp or cover would be helpful. But leaving a boat in the sun for a few weeks or months won't really affect it much. A couple of years, and the effects will start showing.
