According to some Atlassian-published documentation, it would seem that, within the JSM Standard product, users can't configure cross-project/global automation rules. However, in my experience, they can-- with a 500-run limitation, per product. Whereas premium is unlimited.
Assume I had JSM Premium and Jira Software Standard, and I had automation rules creating issues from JSM projects into Software projects-- which product's count would this go against (JSM or Software)?
