Yes FedNow (and RTP from the Clearinghouse) are captured from bank account, but are push unlike debit which is a pull like credit cards. I looked into it for bill payments and there's a FedNow feature to request payment but it's still in very early stages I don't know if it's even implemented for any of the banks that do support fed now already.
Interesting. Services like my property taxes and electric bill charge me an extra fee for credit card payment (which I prefer since it is push and also rewards) but they only offer direct bank transfer as the other electronic method which I hate since it is pull. I doubt I'll seem them adopt fednow though.
My solution for property taxes has been to just set billpay every year to send them a check at the expected intervals.

Precisely why credit cards are a hidden parasite on overall economic activity. They incentivize customers to use to get rewards and then take a ~4% cut of the payment from the merchant. So that's why merchants charge you extra fee they need to make up that 4% cost somewhere and it's either fees or raising prices even though you might not realize it.
