This is maybe a bit of an outlier, but I bought my (5′ 5″) partner a Genesis Borough a couple of months ago for exactly the kinda riding you describe, with added long rambling days out in the countryside. If you hunt around, they were discounted down to about £500.00 in some places.
The main selection criteria for her was getting the best fit, after struggling with a too stretched-out, racy Kona XC bike for a while, and this one turned out to be perfect.
Usefully, it’s all normal sized tubes, so upgrades are easy, although everything works fine as is for now. Not noticeably heavy either. It’s also F&R rack friendly (which might / might not matter).
