What is the best process for qualifying businesses of all entity types for debit cards? I understand it is a credit product, but, what is the best way?

I don’t think debit cards are a credit product.

If I wanted to give businesses “credit cards”, I would do like most large issuers do. That is, base the credit decision mostly on the individual behind the company since that person is going to be on the hook.

Sure, I will still run a Dun & Bradstreet on the business to weed out the worst, but really not as important as the individual when it comes to small businesses.
