I agree with those that have indicated that it's not the breed of cat but the personality of the individual that you need to assess. Yes, there are breeds that tend to be more snuggly, but there are always exceptions. If you really want a kitten then choosing one of those breeds will more likely get you the lap cat you want. But there's the risk that you won't get what you want at all.
If you're open to getting an adult, you will be able to choose one with the personality you want. Then you can decide whether you want a purebred or domestic. Which will lead you to the type of place to adopt from...shelter, a general rescue, a breed rescue organization or a retiree from a reputable breeder.
It seems like you have it all planned out, but have your parents agreed? The reality is that your family will be taking care of your cat while you are in college, whether you're a 2 hour drive away or a 4 hour plane ride. Are they committed to caring for it, keeping it inside, paying for vet bills, are you on the same page regarding food? We often get young people here who are doing battle with the parent that hasn't embraced high quality nutrition.
My personal opinion is that you should wait. I feel it is unfair to the cat to get attached to you and then have you disappear for weeks or months at a time. Then when you finish school, possibly taking it out of the home it has been used to for 5-6 years and moving it to a new home...removing other people that it has become attached to from it's life (your mom, dad, brothers).
If you do decide to go ahead with a purebred cat (now or in the future), please be extremely careful to research the genetic issues the breed may have and what the breeder is doing to ensure those problems are not passed down their lines. We can help with what things may be red flags for breeders.
And last but not least...I vote for Maine Coons. Holly is extremely affectionate, follows me everywhere, wants to help with EVERYTHING I do, she's willing to be held...not just sit on my lap, but cuddled and snuggled and she's a goofball.
Holly, Misty & their friend, Jake, the dog.
Onyx, Callie May, Maggie & Kobi forever in my heart.
Yes, I know I need a new signature pic...someday...
