Discover has seasonal 5% categories that change every 3 months but they're pretty broad like "Gas and Groceries" or "Restaurants and Entertainment".

I have the old American Express Blue Cash card which has some crazy 5% cashback on gas and groceries once you hit a minimum spend during the year. That thing paid out like a slot machine when gas prices were hovering around $3.50 a gallon and I was doing a 100 mile commute daily.
