Scottish Fold

Breed isn't the only factor that goes into affection levels; cats who were raised inside a home with people around feel more comfortable with humans and bond more easily. See Cats Less Affectionate with Family. If you're going to share your home with a cat, you'll need to deal with some level of cat hair on your clothes and in your house. However, shedding does vary among the breeds. If you're a neatnik you'll need to either pick a low-shedding breed, or relax your standards.
