Saddle recommendations depend on riding position.
What sort of riding will you all do. I have a Soma Beuna Vista setup as a city bike. The geometry is sports touring. The handles bars are set up a little above the seat. This makes it semi upright and comfortable.
I also have a wider leather saddle which works for my riding position. If she doesn't want to be leaned over look for upright bars. I find flat bars uncomfortable and prefer swept back ones with a neutral wrist position.
