UEFI BIOS are much smarter than legacy BIOS. They know how to read FAT filesystems and load files from them. No special copy method is required for backing up or copying. What you shouldn't want is cloned FAT filesystem UUIDs. Thus, a freshly formatted FAT 32 ESP should do just fine by simply copying the tree from the original. How much trouble they may be to boot from may depend on how smart your particular UEFI BIOS actually is. The better ones have setup UI that's understandable. Efibootmgr is your friend in managing where the UEFI BIOS should be looking for those boot files if BIOS setup is less competent than one hopes for.
Debian only puts a tiny number of smallish files on an ESP. A normal default installation alongside a Windows installation sharing the 100M ESP typically created for Windows shouldn't be expected to result in as much as 10% of space on ESP to be used by the two installations' required files.
