Hi Todd,
Enterprise Environmental Factors and Organizational Process Assets are confusing and sometimes not easy. They are broadly discussed in the PMBOK Guide and are inputs to almost all processes.
One category of OPAs you mention helps project teams conduct work—policies, procedures, templates, and guidelines. Teams cannot generally change these elements, but can ask management to consider updating them.
Enterprise Environmental Factors are the influences not under the control of the organization or the team that affect the company, the project, and its results. Every organization exists and works within EEFs.

I remember a few questions about using EEFs and OPAs on my exam. Having a better understanding about them will certainly help you on your test.
Best to you,
