I cannot find which hotel brands correlate to the category levels for certificates?
There are several approaches. Start with this list
OUTDATED DISCUSSION: Where can I use my category 1-5 certificate in the USA?
If that's not enough, try this link
Book Category1 Category2 Category3 Hotels
These are just two ways to search for properties in the appropriate categories.
As far as brands go, the certificates apply to any of the Marriott brands as long as the property is category 5 or below.
Naturally that won't cover any Ritz-Carlton or EDITION properties, but it should include the rest, though you will find only a one Gaylord property, a couple Marriott Vacation Club locations, and a few dozen JW hotels (mostly in Asia).
It isn't done by brand so you can score something like a cat 5 JW Marriott
Here is a list that the wonderful bejacob made:
Here is another way to find category 5 or less hotels where you can use your certificate. Select the "Find & Reserve" function in the main menu and input the city/area where you are interested in staying. On the right hand side menu look under "Filter Results" where you will find "Hotel Rewards Category". If you select that option it will show you the total number of hotels in the area that fall under each category. Select the category you are interested in (i.e. category 5) and up pop the hotels. Good luck and have fun with your free night out.
Or if you just want to go top end on the Cat 1-5 certificates, here are all the Category 5 hotels: Category 5 Marriott Hotels Worldwide
