154 CT will definitely be a good size for you. The Proto is my all-around board of choice now. I do a lot of presses and like to butter so it's good enough for that. The Evo is better to press and butter on because of the softer flex, but it also means it's not as stable as the Proto for steeper/faster runs.
Since you sound like you want a board to do a little of everything well, I definitely think the Proto is going to be a sweet choice.
By the time you get really good at things like jibbing, you'll probably want to add another board to your collection by then anyway.
Proto CT all the way for you in my opinion.
