FWIW, here is my advice.

Unless you have boatloads of disposable income, don't buy anything akin to an uber bike straight off. Buy something on the economy side, but with quality parts (e.g. Sora level or equivalent). If you end up really taking to the sport, you'll want to have two bikes anyway (it's always nice to have a second for rainy days or when the other bike is in the shop). If you don't take it up, you've spent a minimal amount.

Personally, I am not a fan of hybrids. I find good old road bikes to be most comfortable over distance because they spread your weight out more equally between your feet, hands and rear end. And they are more efficient. Also, your weight is high, but not so high that you can't get reasonably comfy on a road bike. I had a guy BLOW by me this AM that probably had your BMI.
