alt Hacker NewsUnder "Display & Text Size": "on/off labels" and "increase contrast". "Reduce transparency" is a bit of a mixed bag but is worth trying out.
Under "Audio & Visual", "background sounds" is a built-in 'white noise' generator and can be useful for relaxing / sleeping. You wouldn't want to leave it on all the time, of course.
Under "Touch": "Back Touch" lets you map a double/triple tap on the back of the phone to various actions.
There's a lot of other neat features in iOS Accessibility (eye-tracking control! automatic captions! sound recognition!) and I'd encourage you to poke around to see what's available.

As for Reduce Transparency, next iOS version has a proper slider to adjust the transparency of Liquid Glass - worth playing with for anyone on the beta
I love the background sounds feature. You can add a shortcut in the control center to turn it on and off. I used it a ton when I lived in an apartment with particularly noisy neighbors
