The Specialized Sequoia is affordable and offers a road bike style frame with a slightly more upright seating position.
If you prefer to not have the suspension seat post just replace it with a decent carbon one.
It comes standard with 700x26 wheels, however feel free to go up to 28 or down to 20.
My partner and I purchased ours six months ago and are very happy so far. Also has plenty of brazeon for panniers or mud flaps if you require that kind of thing.
As everyone else says fit is the key thing. I'm sure a local bike shop near you would stock it or some other decent alternatives!
I apologise for not answering your other questions specifically. It's up and beyond my own personal experience...
