Identifying the right taxonomy is not only an exercise in naming things, but also building the appropriate data structures and systems in your programs. I think this exercise is incomplete in the absence of studying how these nouns interact with one another.
I don't think that a loose-hanging 'payment intent' evokes a particular emotion, without its constituents' (credit cards, direct debits, cryptocurrencies) relationship to other nouns (customers, invoices, taxes, countries).
