Thanks to everyone who has made this process so easy! I've gone from a fresh, out of the box NUC8i5BEK to a (nearly) fully functional Hackintosh in just a few hours.
One thing I want to contribute is a reasonably simple fix for bluetooth not seeing any devices. The consensus online seems to be that, should this occur, you just need to boot into Windows to get the stock bluetooth card to turn on. Having gone straight from the box to macOS, that wasn't really a great option. Instead, I created a bootable Ubuntu thumb drive, rebooted, selected the "Try Ubuntu" option so it boots directly off the thumb drive, and then opened the bluetooth settings (just search "bluetooth" in the desktop search box). I could immediately see all of the discoverable devices in my area. I rebooted back into Mojave and, as luck would have it, that worked and I can now connect to most devices. I have a Xiaomi BT mouse that won't connect, but that seems to be somewhat common with non-Apple mice. I was primarily concerned with bluetooth audio, and that works fine now.
If you're unable to see any bluetooth devices, give the above a shot. It's quick, free, and doesn't take up a USB port for an external dongle. I assume I'll have to boot into Ubuntu again if the NUC ever loses power, but that's simple enough.
