You sound more like you’re in the ideal size range for the rebel. With your weight I suspect highway speeds aren’t going to be realistic, but for getting around town a rebel is going to be just about right. Also, from experience, highway riding isn’t where the fun is on a motorcycle. The fun is in riding the twisty back roads.
I’m a few inches taller than you, and I ride a Honda Magna. The seating position on a Magna and a Rebel is identical. You won’t feel cramped up. It’s like sitting in an office chair.
The only real beef you’re going to find is that the seat is uncomfortable after a couple of hours. That’s just a Honda feature for their lower end bikes (which the Magna is in terms of comfort features). Chances are you won’t be taking two hour rides for a while, so don’t sweat that.
