I'll give you my opinion. Others vary.
There's no way that the OS plus software, config and cache take more than 1TB, so I make my root partition on an NVMe either 1TB or 500GB. Then I bind mount the rest of the mount points with space on a 14TB, 7200 RPM spinning rust. That 14GB is of course formatted GPT, and because it doesn't boot, it needn't have UEFI for the spinning rust. Meanwhile, the small NVMe or SSD doesn't need GPT, so it can be partitioned the old MBR way So if, and this is a big if, your motherboard supports MBR well, in my opinion this is currently the best way to go.
However, note that some motherboards make it very difficult to boot from USB or DVD via MBR, sometimes requiring a trip through the BIOS setup screen. Also, many or most bootable DVDs and USBs can boot MBR *or* UEFI, but not both.
As far as I know most machines made in the last 5 or so years do not support anything other than UEFI booting anymore. Servers seem to be still offering it, but as far as I can tell starting either this year or next year, they are going UEFI only as well. At least if they have an intel CPU. -- Len Sorensen
