Drops, braze-ons, and 'a bit livelier than a Galaxy' will be any of the current range of bikepacking/gravel bikes: Kinesis, Sonder, Mason, Open-Up or a dozen other models.
"Women's geometry" is a bit of a red herring: it usually seems to mean a shorter and taller front end, with narrower bars if you're lucky and shorter cranks if you're really really lucky. Oh and a different saddle, but does anyone male or female ever ride the saddle they buy with the bike? Fortunately, the bikes I mentioned above are all a bit shorter and taller than their pure road equivalents and it can mostly be sorted with component swaps anyway, so buy from an LBS and get them to swap the bars for you.
Crosstop levers: not a standard option but get the LBS to put them on while they're swapping the bars.
Disc brakes: aah, here's the rub. All the bikes I mentioned above will come with disc brakes. If she can put up with those, her choice is expanded several times over.
