I think this can vary greatly, depending on the prospective employer. I would speculate that many companies in the healthcare industry indeed require some sort of criminal background check. However, there could be considerable variation in terms of the number of years they examine (the past 7 years, for example, versus 10 years) and the locations where they secure this data (your current state, past states, etc.). And in my experience, credit checks are less common, unless you will be handling funds/financial data, and have monetary responsibilities.
If you have a conviction, remember that you may not actually need to disclose this prior to hire, but if you must, it will likely show up on the application itself. Different states have different rules regarding what candidates must disclose regarding past convictions, when, how, and to whom.
I would suggest asking the recruiter about the process in a very general way. Find out the new hire/onboarding steps, and if there is any documentation you can read or complete ahead of time, if possible. They may send you the background check consent form, itemizing what their company will perform.
If you have a specific question or concern about the background check process, the recruiter may be able to discuss it with you in confidence, and provide the information you need.
