Using this value
Either form of this value goes in the google_product_category attribute: the numeric ID (499874) or the full path ("Hardware > Heating, Ventilation & Air Conditioning > Air Ducts"). Both are predefined values for the same category. The ID is the sturdier of the two, because renaming any segment above this one changes the path text and leaves the number alone.
Bear in mind that google_product_category is an optional attribute. Google assigns a category automatically, and your value is treated as a signal rather than an override. When an override actually applies.
