No clue what card to get next

Hey! Just like what the title says, I don’t know what card to get next. Currently have: - Discover It (since Sep 2022), mainly used for gas - Capital One Quicksilver One (since March 2023), used for every day purchases - Capital One Savor One (since Sep 2023), used for dining and going out

FICO is ~745. My goal is really to just keep building credit and keep getting cashback, but I do have goals to get more into traveling and using credit cards for travel rewards

So ya… What would be your recommendations? Thanks!
