I haven't a lot of experience here but I always thought the general rule for boot disks is: classic BIOS -> MBR and UEFI -> GPT.
After some more research, I think I found the definitive answer to the problem. It's a little bit more complicated.
UEFI -> GPT
BIOS -> MBR
BIOS with disk > 2^32 sectores (2 TiB) -> GPT
And searching for this, I stumbled over docs.centos.org, whose existence I ignored. Must be relatively new:
https://docs.centos.org/en-US/centos/install-guide/StorageSpoke-x86/
See section "MBR and GPT considerations".
