The best way to arrange them would be by the little icons on KC's website, and not the subtypes in each of their entries because that part is confusing as fuck as shown in the OP.
It would put Dwarves and Elves as Demihumans for example (the red icon), while classic demonic looking mamonos like succubi, imps, etc would fall under Demons (the purple icon). More human looking ones would fall under Majin (icon not in this image).
This does mean arachnids are also placed in the same category as insects though, but I feel like this is where the subtypes come in handy. They should be used as descriptors rather than a category.
