Greater opportunity, yes; however, cash is still legal tender in the US and it used to be illegal to not accept it as payment (this may have changed). And, as the payer, make sure you get a receipt so they can’t screw you and if the landlord doesn’t pay taxes, you’re not culpable - it’s their responsibility, not your’s.

Cash is fine. The receipt is important, though, for a number of reasons. Not many people are going to go withdraw $1,100 just to pay rent, unless they’re getting a discount for cash, which is a good indication there’s some tax dodging going on.

Even if you trade sex for rent, get a receipt saying you paid your rent.
