Credit cards for travel

What are some good credit card options that would benefit someone who travels often? Something with an unlimited/decent number of lounge access, or offers on flights, or rewards like miles, or maybe even offers on hotel stay? Basically anything that helps me in terms of travelling

I tried to search online, but I am hella confused.

PS - often as in a week long trip every ~two months or so, and mostly domestic, if that helps in your recommendations

Thanks in advance! 🙏
