Being in CT and having high humidity and mild temps in the summer, I would say all your CVs would love full sun. I would keep the more blue/purple CVs in more dappled sun, since their pigments arent as colorfast as those reds, yellows and oranges.
I would say that hot sun and heat is more tolerable to some CVs, but in my experience all CVs love temps 65-85 and half day sun. There are some that are more tolerant of less than ideal conditions (all day sun or more shade), but tolerance is far from thriving. The rule of thumb that if you are comfortable outside, then hibiscus will be too, it true.
Sleeping beauty is the only one on your list that looks much better in mostly shaded conditions.
