You're not going to avoid screens. Your best bet is to compare all the mainstream options. A lot of manufacturers have come to the realization that, while screens are good, some easily accessible and tactile knobs and buttons are important. So I'd just look at the usual suspects, like another CR-V or the RAV4. I have both, actually.
Obviously, avoid Tesla and all the cars that think you should operate everything from a touchscreen behind multiple menus, which is absurd.
And you never need to use Apple Car Play, but it's pretty intuitive, so if she were my mom, I wouldn't give up on that just yet.
I'm no greenie by any means, but I also recommend the hybrid versions of these cars. (I have it for both.) There's just no reason not to at this point, and there's absolutely nothing that she would need to do differently because it's a hybrid.
