Cash for most things, and just use a card like normal otherwise.
I don't really see the appeal of contactless payment, pulling a card out really doesn't take much time.
Google Pay (Google Wallet) actually also has virtual number so my real card number won't leak in many cases.
Just having to take your phone with you is quite comfortable. Your phone is probably the pocket-sized item you are unlikeliest to lose.
Cards are "contactless payment" these days.
