Some CC will pay you to use them. For example, the Citi Double Cashback card gives you 2%

There are other cards that will give more but are usually limited to certain categories
Chase INK - 5% at office supply stores such as Staples & Ofiice Max/Office Depot 9but it's a business card)
Discover - 5% on rotating categories. Right now it's 5% at grocery stores. Max $75 cashback for $1500 spend.
Chase Freedom - 5% on rotating categories. Right now it's 5% at drug stores like Walgreens or CVS. Max $75 cashback for $1500 spend.
Google for "best cashback credit cards" and pick the one the works the best for you. You'll probably want to start with Chase because they have a rule that they will deny your cc application if you've opened too many other cards recently (google 5/24 rule)
Know that cashback is different from the signup bonus.
Watch out for cards the say "x", "times", or "points", as these are not always the same as "%". They can be worth it, but it makes cards harder to compare.
Good luck!
