I'm not visually impaired myself, but I'll answer with what I know. There are many accessible forms of entertainment which are normally thought of as heavily visual. Many popular movies and TV shows have what's called an "audio description" option, where a narrator describes what is happening visually in between existing dialogue.
$1Most Netflix originals will, for example, have an AD audio option in the captioning/language menu. Hell, that's how I "watched" most of Stranger Things on my daily drives to and from work.
With some assistance or equipment, gaming can also be accessible. Check out
$1 from my buddy Sightless Kombat.
As far as what people find to be "most engaging", that is indeed a little silly to ask. Everyone has different tastes. Some people like sci-fi games, some like rom-coms, some can't get enough anime. Visual impairment is not going to change someone's individual preferences much.
