Accessibility considerations in Cp 12?

Hello, group!

May I ask, if anyone can share accessibility info about Cp 12?

I embed subtitles on all of my material (I do this as I create slides/videos etc, because I think after-market subtitles are icky), and I consider colours (for colour-blindness) and font size and choice for dyslexic and visicion-impaired users. Are there other areas that I could consider, or guidelines you can recommend?

With drag-and-drop and T/F and Radio button quizzes--are there accessibility considerations for those who have trouble with mouse operation?

In terms of Cp specifically, is there an option for an image to be narrated/described for the visually impaired?

(I don't really like the quick, robotic voices of image-describing software, but I am happy to learn about what options we have in Cp. If it's all terrible, then I could always create a course with a separate version where I narrate the images myself...)

Thank you in advance.
