Categories should be accurate and easy to understand. Keep the hierarchy flat, put similar things together, make the structure apparent. How hard could it be? It's not so much hard, as time-consuming. You also need to make sure the IA matches the users' mental models. And has a consistent navigation. And the words you use describe the content in the ways that visitors understand. That's all.
For the toy store SAAS e-commerce platform I worked on, "Shipping" was the number-one search term in our Help System site logs, and shipping setup delayed launch for about half our customers. The standard approach was, "Needs More Help Video!" My approach was, "Make it Less Baffling!" Configuration should be simple, and anyone should be able to figure out their choices.
BEFORE: Many bad choices, arbitrary names, and repetitive descriptions.
AFTER: Usable choices clearly explained. Choices and setup on the same screen.
Shipping configuration was under "Store > Shipping Module," but activated in the "Admin > Configuration" panel.
