I disagree with the suggestion that you can't get anything bigger than a 25mm tyre on some road bikes. It depends on the geometry. On most of those the OP has linked to, I don't think a 28 would be a problem, if he needed it. And anyway, I ride over some rough surfaces on 23 and 25mm tyres with no problem.

OP, with regard to specific models, I reiterate that there is nothing to choose between them with regard to quality for the money. As for the road bikes, note that the Trek Domane you linked to is their women-specific model. But they do standard versions too, they're a fine bike. The others are great too. The Cannondales are probably the most aggressive of those you've linked to, (and the ones least likely to take a slightly wider tyre) so I might steer you, as a new rider, in the direction of the Giant, Trek or Specialized. Cannondale fans will tell you different, of course...

It comes down to sitting on a few and deciding what you like.
