There is no additional charge for SSM parameter store but rate limits apply (and I can't find out what they are). I have read accounts from people on HN who work on large AWS accounts who have been bitten by this. The secret manager bills per request, so presumably that means they'll happily serve as many requests as you want. It also has some nice tooling around cycling secrets. It's an important distinction when choosing which one to work with. To contribute an additional idea not seen in this topic yet - my application predates both these services so it just reads from a JSON file in an s3 bucket that is encrypted at rest. It works just as well as all the above.
