How will this impact things like Venmo or Apple Pay, both of which currently charge some % for instant transfer to your checking account.

Personal opinion: significantly. FedNow instant payments are a penny for up to $100k transfers, with the eventual plan to support up to $500k transfers.

I don't see how it would impact Apple Pay, for example. In Australia, we have instant payments already, and Apple/Google/Samsung Pay is used alongside it - completely separate.
