Given that you need AWD, the usual suspect would be that you should get a Subaru. The Impreza will be most economical of them. Outbacks and Foresters are larger/less economical.
Alternate vehicles in the Outback/Forrester size/economy would be the Mazda CX-5, the Honda CR-V, the Toyota rav4, etc.
You don't give a budget range, so I'm giving you the cheap new vehicle options here. Obviously you have a lot more options when you get into more high end cars as a lot more of those tend to be awd.
