Since posting I looked at the AAA website and found a
printable list of autos (in a section open to nonmembers, too) with features that are helpful to those with certain conditions such as diminished vision from cataracts and glaucoma, and physical limitations due to arthritis, etc. I also read that cars with a digital display of speed on the dashboard, as opposed to the traditional speedometer with a needle against the dial, can be helpful to those with diminished vision.
