Travel to Brazil out of NYC - best credit card

Hi everyone!

So I will be travelling to Brazil about 3x per year (as well as my sister), and I am inexperienced and learning how to utilize credit cards efficiently. I am based in CT, so flights will most likely be JFK to GRU. If loyalty will give me the best ROI, I don't mind getting a company-specific CC. I have looked at Venture X, Delta AMEX, Chase Saphire, etc.

I am going to spend $3,200 on tickets within the next week and would like to get the rewards for those! I like the idea of lounge access, but not a definite need. I will also be getting Global Entry (since I know some offer a $ credit).

Please let me know what you guys think will be my best option!
