If you know you are on RHEL or Centos what are the ways to determine
which version you are on?

Well it depends upon why you want to know.  Most reciently i wanted to automatically

yum version | grep '^Installed: ' | sed -e 's!^Installed:[ \t]\+\([^ \t/]\).*$!\1!'

      yum:
        name: redhat-access-insights
        state: present
      register: install_insights_task
