As to the RH decision to default to a legacy boot / MBR oriented
install based upon size of disk ... words fail me.
I don’t think that it chooses legacy boot based on the size of disk, but
based on how you booted the installer. If you booted from the installer as a legacy boot item, it installs as a legacy bootloader, but if you disable the BIOS option to use a legacy bootloader, it will boot the installer as a UEFI boot and choose to install a UEFI grub2 setup.

And the same seems to be true about other UNIX like systems, at least Debian and clones, FreeBSD and clones.
This has been my experience as well. If the installer is booted in legacy mode then it will install as it needs to for a BIOS system. If it is booted in UEFI mode then it will install as needed for a UEFI boot. Trying to boot in legacy mode and install for UEFI boot is fraught with a lot of manual complications. IMO it's not any more complicated than understanding the limits of legacy BIOS booting and all the workarounds that have been stacked up over the decades to keep it working.
