I think that Jamis is beautiful!
I can completely recommend the Specialized Vita, which is on the faster end of the hybrid spectrum. I'm not sure what the pricing is in dollars however. I learned to ride at 43 on a comfort bike, moved to a Vita and was just blown away by how much it changed and inspired my riding. It's not a road bike, but as Muirenn said will help you find your legs, and then when you do want a road bike as well you can just pop a rack and fenders onto the Vita and have a great utility bike too The Specialized Dolce might be an option too but I'm afraid I have no ideal on pricing.
Welcome to TE and congratulations on your weight-loss so far!
