If you like cash back - look into US Bank Cash+ card 5% on two categories you pick.

Also, Citi Forward 5x TYP on Dining and Bookstores (amazon). You can get cash back in the form of a (100 points = $1) check made out to your mortgage or student loans - though some report success, if you don't have a mortgage to just name the bank where you keep your checking account, the check comes payable to that bank and you just deposit it. They also have gift cards that at times exceed the 100 points =$1 rate.

That said, the value to be had from applying for cards, hitting spend and harvesting a bonus exceeds the category spend perks. I started in January and I have picked up about $5K in card bonuses in that time (100K AA; 55K UA; 60K DL; 40K US, 70K Marriott; 115K HHonors; 30K SPG; 50K Citi TYP; 2 nights Hyatt).

Going forward, my basic plan is Amex BCP (groceries, 6%); Forward (dining + amazon, 5%); whatever card I need to hit spend on (everything else). When I get Ink Bold I'll move telecom and office store purchase (5x UR) to that card.

With your spend you are leaving money on the table if you grabbing bonuses.
