This forum is full of roadies who go on daily rides of significant lengths, and race, where being aerodynamic and fast plays a big part in enjoying the ride and having the endurance to complete it.
Fitness bikes are made for the basic idea you've presented--a comfortable, fast commuter or a 8-10 mile rip around town to get in shape.
You really need to ask yourself whether you want to get into serious endurance riding (40, 50, 100 miles, whatever) or just blast around town for fun. For the former, the road bike is the only option. For the latter, you could use either, but driving a tack with a sledge hammer is overkill.
Fitness bikes have comfortable geometry with road bike rolling resistance. I would not want to ride one for 50 miles into the wind. But if I wanted a fair-weather commuter and to take out on rides with the kids or whatever, I think they're a great option.
Before my girlfriend got really into cycling, I suggested that she get a fitness bike. Once I realized that she really was interested in coming along on 20+ mile rides, I suggested a road bike instead. It took her a while to get used to the more aggressive geometry (even though her road bike has a higher head tube and not much drop), but now she can and has done rides of lengths 4x of what she was comfortable doing on her hybrid.
So, while opinions here are plentiful, what is really important to you is to decide where and for how long you're going to ride before you pick a style of bike. Just like you wouldn't use a semi truck to move a single refrigerator across town, you also don't want to try to move a hundred of them at once with a pickup truck. Ideally you'll have the tool for the job, but of course some deviation is sometimes necessary.
