What are those strange characters in the footer of your message, after the "--" line?  I can't read them as anything rational: look like hexadecimal codes.

I run FreeBSD and NetBSD, using GPT and no traditional BSD disklabels that would drive me crazy.  I find OpenBSD not compatible on my system.

LiveUSB OpenBSD from can't read or recognize my GPT-partitioned hard drive, and didn't recognize my Realtek Ethernet chip, 8111E/8168, haven't fully tested with wi-fi since I copied necessary firmware using FreeBSD. 

I usually use Super Grub2 Disk, available on earlier versions of the System Rescue CD written to USB stick, but am trying to move over to UEFI boot, need to more deeply study what I can do at FreeBSD loader prompt or NetBSD boot prompt.

What/where is the gptboot you might want to install?  Is it in FreeBSD ports, base system, or somewhere else?  I notice FreeBSD >= 12.x has efibootmgr in base system, not avaliable in NetBSD base system or pkgsrc.

I notice /boot/gptboot in FreeBSD base system, that would not be a separate installation.
