What additional protections can I get from integrating free ipa into my infrastructure

Additional to what? Perhaps you need to explain in more details what are you considering?

Otherwise, https://www.freeipa.org/page/Documentation contains plenty of information, including links to Red Hat's product documentation for RHEL IdM. I also suggest to read RHEL Blog articles by Dmitri Pal: https://www.redhat.com/en/authors/dmitri-pal, they go in detail for general architecture and considerations of how to deploy RHEL IdM (FreeIPA).
