I accidentally linked to the same bike twice. The first bike is this one:

I can't get the geometry charts to come up. but it appears the less expensive option has a higher head tube so possibly shorter reach, meaning that would be better. But I'll load another browser and check to be certain.
Regarding men's versus women's, every bike's geometry is set up differently. You really have to look at the effective top tube, head tube height, stack, reach, and head tube angle for size comparison. It's pretty normal to change out bars, especially for women, you don't want to eliminate an otherwise good option by being hung up on whether it's a men's or women's bike.
Also, the Trek Lexa is available in size 50, and size 52, no size 51. So can't really tell from that what bike fit you the best. Do you have any other information on what bike fit you well? Same with the Raleigh.
FWIW, the
Giant Invite 2 reminds me most of the Trek Lexa for frame materials and overall fit and probable feel. The steel CX are nice, but would be heavier, and aluminum cx bikes tend to be quite practical.
