You are correct that knowing the name of something can teach you (or help you remember) more than just the name. But if you didn't know that 'kiwi' is onomatopoeic, knowing the name wouldn't tell you what the bird's call sounds like.
Onomatopoeia also depends heavily on language and culture. In other words, knowing an onomatopoeic name for something only tells you what somebody thought it sounded like, at best.
A name is just a name, even if some are better than others.
