What does your workflow look like? Are you using global transitions?
The Suite Utilities for Jira add-on would give you the ability to have workflow conditions based on the value of a field or workflow status. I understand buying things is usually a pain, but this adds a lot of functionality that I couldn't live without as a Jira Server admin.
Without an add on, building your workflow to have these conditions won't really be possible, but you can do things with permissions instead (requiring a special role to close issues).
