Boot Configuration/Approach options for MultiOS

I've got a removable drive tray with a spinning rust drive, and two
nvme w/ enclosures.

I'd like to install Linux/Windows/BSD in a multiboot configuration, on
a single drive.

What options or approaches are available?  Let me know even the bad
choices.

I'm thinking of either doing triple boot with Grub or Possibly a
Single UEFI image for Linux and BSD. (is that possible with BSD?)

Is it possible to load a UEFI image with BSD?  Or will I need to use
grub?

I'm not familiar with the bootloader for BSD.

Please offer any and all options, even if they may not be the best
choice.

I use refind to manage a multi OS setup, which supports most systems
except openbsd.

I'd go with rEFInd. It can auto-detect installed operating systems and
add them to menu.

I had linux with refind on nvme in my laptop, and freebsd on external
hard drive.

When i started laptop with external hdd plugged in, refind detected
freebsd there, and added it to menu.

Also, it does not boot freebsd directly, but rather than boots freebsd
bootloader, which then boots freebsd, so you still can add things to
/boot/loader.conf

I assume it boots windows in the same way

Where does rEFInd write the boot menu?

You can manually add entries in /boot/refind.conf or something like
that, but the auto-generated ones are not stored anywhere. On next
boot they are auto-generated again, if that's what you ask for

I guess I dont understand where rEFInd runs from - its on the boot
sector of your HD right?

rEFInd is installed just like grub in UEFI mode, to something like
/boot/efi/BOOT/bootx86.efi, and then you need to point to it in UEFI
settings. Or in some cases package installing refind can tell uefi
where to look for it, since you can modify some uefi settings from OS.
