Ave Maria Mutual Fund & Aquinas Funds - I'm not an investor so I have no clue how they perform. I think they only invest in companies that are pro-life. Ave Maria Mutual Funds can be found on bigger platforms like TD Ameritrade or you can invest with them directly.
Credit Unions - You would have to check where you live. I think the credit union in my town was originally created for Polish immigrants but now it's under different management. It's similar to those Catholic universities that have 'Catholic' in their name but no longer have anything to do with Catholicism.
I doubt any support traditional churches. I guess if you need a checking account and debit card then credit unions are a good alternative to banks.
It's strange how very few banks are dedicated to Catholic values. There were many banks and credit unions that were founded to help Catholic immigrants. Bank of America was founded by a Catholic and Italian immigrant. His story is actually kind of nice. You can read about it here
