Need Guidance for 2nd Credit Card to be used for travel

Hi all! I've been researching different cards and wanted to get some recommendations on a good travel card. I travel for work at least once a month (1-2wk at a time) either domestically (U.S.) or internationally (Europe). I'm starting to increase personal travel as well. Discover It has been my "everyday at-home" card for years, but otherwise, has not been reliable across Europe. The primary purpose of this 2nd card will be for travel (airfare/transport, hotels, dining, shopping).

Important factors: international reliability and no FTF. No preference to cash back vs points. I just want to maximize rewards for every purchase. Open to reasonable AF as long as the rewards structure is worth it.

I filled out the template below, thanks in advance!
