Any category does not require approval to sell?

Hi I am new to Amazon seller, I wanted to list some products on Amazon first but when trying to list a product and chose “New” then it required me to click “Apply to sell” and to provide proof of the purchase of products and even 10 units. Tbf I have not purchased any product yet, I wanted to see the market reactions first and don’t want to stack up the products that no one would buy.

I’m not sure if all categories/products require approval, or Is there any category doesn’t require approval to sell?

Thank you!
