Alright, just a short update on the issue of tire sizing the Ruby. I borrowed home with me a worn Maxxis Detonator tire today. Dimension is 700x32 (32x622) fitted it to both wheels (80 psi) and found the following,
Front: Just barely scraped the fork crown, maybe 1mm and just cleared the caliper. Too much drag. Not compatible.
Rear: Cleared the seat stay by 1mm. Cleared the caliper by more than 1mm. No drag. Compatible.
The Maxxis was just something i used as a guide, not planning to buy that tire. Maybe i`ll have to install different tires, maybe not.

Any road bike in the last 10 years and most before that will way less than 10kg (22lb). My current Trek weighs 8.5 and that's with stock components on it. The good news is SRAM mountain bike and road is interchangeable and has the same cable pull. That means you can put SRAM mountain bike shifters on a road bike and use a flat bar. That's the option I would go for. Sorry if this has been said, but I don't feel like trawling through four pages of text at this hour of the morning. I would be using grip shift in this case for an elderly person but they have other options.

Give yourself some extra millimeters of clearance. 1mm is super sketchy, small enough that slight loss of wheel true can bring a ride to a grinding halt, and even small enough that it might rub under hard pedaling or riding out of the saddle.
There are still some entry-level bike-shop road bikes that exceed 10kg in showroom weight. On disc models that's even true for some that are close to $1000.
That depends on how many cogs you have in back. Their 10-speed stuff uses the same cable pull between road and MTB, but not 11-speed.

As to stem length and frame length a women's specific bike should resolve this issue.

You might find something in a 700 x 30c. Typically that is a cyclo-cross size, so they are designed more for off-road. You did mention a little bit of tread for slippery conditions, but maybe not that much. There is a Challenge Strada Bianchi tire in a 700 x 30c that looks interesting. If a 30mm won't work the next stop is a 28. But that is not bad and there are a ton of good touring tires out there.
