We ship perishable products that must be shipped Express. I would like to put a rule in my Standard shipping so that the customer is not offered a standard shipping option if a product from a specific category is in the cart. This is what I tried but I must be missing something.

NAME=”Perishable Products”; Categories==list(1,5); NO SHIPPING

If you don't want to provide a shipping rate for a particular shipment method if a product from category 1 is in the cart, the proper check in the advanced plugin is "1 in Categories". Also, "NoShipping" should not have any space.

If I wanted to use multiple categories, then would it be

NAME=”Perishable Products”; Categories==list(1,5); NOSHIPPING

That means that only categories 1 and 5 are in the cart, then no shipping is allowed. As soon as a product has another category, the list will be e.g. list(1,3,5) and no longer equal to list(1,5).

What you rather mean is:
Starting with plugin version 4.0 (the beta/testing version 3.95 of that version is available on the homepage) there is also the function intersection that will give all elements that are in two given lists (in your case the Categories list and the list of disallowed categories). The rule could then be:
