The world is filled with detail, tailoring text to meet the needs of people unable to grasp that detail does not remove it - It obfuscates it.
Sometimes simple and direct language is good. Sometimes it makes the entire conversation devoid of usefulness or meaning.
Work to understand which context is appropriate for what you write.
Example(and opening myself up to criticism):
"Kyra is autistic and very deaf. She was born small and much earlier than she was supposed to. Because of this she has trouble seeing, hearing, eating and sleeping. Her hand shakes so much that she cannot use sign language to speak much at all. Her parents think she may know a couple of signs, but no more."
Some of these make writing better. Many of them just leave words out and don't say as much.

There is a lot of stuff around us. Using words meant only for people who do not like a lot of stuff does not make the stuff go away. It just hides the stuff.

Using simple words can be good. Sometimes it is not good enough.
> Work to understand which context is appropriate for what you write.
Use words understood by the people you are writing for.
Your first 3 re-writes all lose some of their meaning in the simplified form. The last one is basically fine.
They reminded me of Hemingway's simple, declarative style. I know some people like it, but I always found it somewhat lacking for creating a sense of emotional connection to the characters.
