My mother has a very similar condition and has been recently declared legally blind and her vision worsens by the month. She primarily uses a Vision Buddy (https://visionbuddy.com/) for screens and for books, she has an audio book player that connects to the Library of Congress where she gets free audiobooks (https://www.loc.gov/nls/enrollment-equipment/equipment-neede...)
Have you looked into streaming devices so she can watch movies and tv with audio description? I'm totally blind and the availability of audio description on all major streaming services has made tv watching a lot better for me.
Descriptions are read by a human narrator. Description only occurs when there is no dialog. According to my sited wife it's not that distracting, she got used to it after a month or two.
