Best travel card recommendations?

Hi! I’m considering getting a travel credit card as I am booking 3 domestic trips for the upcoming holiday season. All 3 flights will likely be from NYC (typically out of JFK) to SF. I am not loyal to one particular airline, but do generally enjoy Delta. I don’t travel a ton throughout the year but do typically book about one vacation (sometimes in US but otherwise somewhere international) and often travel to CA for the holidays (2-3 trips).

I’m not a huge premium experience traveler but do enjoy middle range accommodations (working with a budget but not looking to be uncomfortable haha).

I already have a simple cash back Amex card but looking to get something new that makes sense for these upcoming flight purchases.

Happy to answer any questions that may help. Thanks so much in advance!
