AFAIU if you are looking for centrally manged setting you need to use sudo.
With su and HBAC IPA can just control which user can authenticate using
"su" but not for local users like root.

I think that if the oracle user is centrally managed you would be able
to define an HBAC rule that would prevent oracle user from doing su on a
group of hosts, but I doubt that this is what you want.
Seems like sudo will give you much more flexibility.
