Doing a better job of RHEL 8's published graphical installer could be done, but it would no longer be directly Red Hat based. Frankly, I gave up on the things for large environments, and published PXE setups with kickstart files that had *much* finer resolution of deployment, especially using multiple %post scripts to keep the operations in sane source control, to set varieties of PXE configs for distinct setups, and that did basic things like running "yum -y update" or "yum -y install epel-release && yum -y install [ useful bits ]" as needed. Since what actually gets installed by the RHEL 7 or RHEL 8 option is never explicitly listed, it's useful to do a reference audito with "yum list" right after the system is built, and keep a copy for reference with the different selected options. This is where "infrastructure as code" becomes your friend, because you can keep copies of this stuff in a relevant git repo.
