If I simply focus on the immediate query we can enhance it by the following -
Currently categories/order as a metric is not sufficient. It blinds us to any outliers. We can also look at number of orders/users and create cohorts based on range of low intent to high intent consumers on the platform. This way we would remove those 1 and done's or users who might have hit multiple categories in one order but maybe just 1 category in another order. And then use this data for customization, recommendation, #count of items in a category, discount offering etc.

I think after that we can dive deep into the category and items bought within them section. See for each category what items are the most popular across the board and then also see cross selling of categories.

The above will give you very basic information metrics of your platform (like User quality & Popular inventory ) before you even dive into building hypothesis, generating creative ideas or experimentation.
Once you talk about this ( as a data expert) then the conversation can be carried to bigger ideas.
