You need to provide this metadata on the setup intent when you create/update it server side -- it can't be provided during that client confirmation like you're asking

I can provide a metadata when I create the setup intent using stripe.SetupIntent.create( metadata: {"eg" : "123"}) on the BE, but it doesn't show up on the payment method after I have submitted the setup intent on the FE to save a payment method using the stripe.confirmSetup().

No, that would need to be applied after the fact by your integration if you want it to propagate there
