If the UEFI firmware follows BootOrder (not all do), it first tries to 
boot from a diskette drive (0001), then from the WDC SSD (0002), then 
from a USB storage device (0003), then from an optical disc drive 
(0004), then from the network (0006, then from the Sandisk USB drive (0007).

No, it tries to boot from the "removable media path" 
/EFI/boot/bootx64.efi in the EFI partition.

No, I mean "WDC WDS200T2B0C-00PXH0" and "PM981 NVMe Samsung 512GB".

Yes, unless GRUB monolithic image grows ridiculously big or eventually 
switches to the BLS (Boot Loader Specification) which needs to put 
kernel images and initramfs's into the EFI partition.
