Any of the bikes you tried except probably the 150 will do freeway speeds without a problem. I’m your size and ride an `06 Ninja 250R. I’ve been on the freeway several times and took it up to about 80MPH without a problem. The little bike likes to rev so it seems a little stressed at first until you realize that you are just starting to get into the meat of the powerband in 6th at freeway speeds.
Personally I’d consider a used bike for your first to save money. That way its easier to upgrade towards your “dream bike”.
