With Wise and Revolut you are OK as long as you can pay with card, but card payments in Thailand are far behind a lot of other countries.
Some shops don't accept cards at all, some accept only Thai issued cards, some add 2.5 percent or 3 percent when you pay with card.
So you need cash or Thai QR prompt pay.
Cash you can get with your Wise or Revolut card at ATM of course, but high fees.
Best indeed is to take your own foreign cash and exchange at Superrich.
My solution is transfer money with Wise to the Thai bank account of my Thai girlfriend when we are at ATM and then she gets the cash for me.
But it would be nice to just have the Thai QR prompt pay, I hope Wise will also support that one day.
