This is a tricky one which I have been trying to help a friend with. the conclusion we came to was my wifes old mountain bike (which was a loan but not for sale). Its rigid, great components and light. The riding position is fine touring or off road.
Its hard to find a modern equivalant, my friend didn’t really have the moeny for a rigid mounatin bike, which are a rarity at that price
all the big brands do lovey hybrids which would do, but for that height of woman I think that 26″ inch wheels make sense. Also IMHO alot of big brands have gone too short on the top tube for a rather sit up and beg round town riding position
quick random thought I wonder if an Isla bike would do……
