Hi Frodde,
For your first question, you don’t need the PRO version to make B) look like A) – to make that you just need to set your product permalink base to the custom base: /products/%product_cat% .
However, if your product belongs to more than one category and you want to choose the category that will be used for the permalink – then yes, you need the PRO version.
For your second question, the answer is yes. For example, if your product is under a subcategory, then by using the PRO version your permalink could be https://www.site.com/products/category/subcategory/product
Best,
Yaniv
