How do you choose which payment method to use? Is there an app or website to know the best option?

There are so many ways to pay that I am now getting anxiety.

Say, if I want to buy some shoes on asos, I could use my posb creditcard, dash visa, grabpay card, go through shopback or google pay or fave, maybe plus!, also revolut has something going on now, sometimes ez-link, and I'm probably forgetting some.

Is there a website/app in which I enter "asos" or whatever and it tells me the one that gets me the biggest benefit? Or how do you normally do it? Thanks!
