Only time I use cash is for the taco truck that doesn't take cards.

It seems like cashiers are shocked whenever folks pull cash out of their pockets lol

I use two Chase cards. Pay off each every month.

Chase Freedom has 5% cash back on rotating categories. This quarter, it's gas. Other times it's stuff like grocery stores, department stores.

Chase Sapphire Reserve. Big annual fee ($450). But the rewards make up for it. 3% back on restaurants and travel.
Airport lounge access (ballin!!)
Trip delay insurance (they paid for my hotel and food when my flight was cancelled).
They pay for TSA pre-check and global entry
