@Going Bald, @cmorellato, thanks to you both for your replies and your patience. I did manage to get the Multi-Boot working finally and I am very grateful for your help.
I think that the Windows drive was formatted properly as UEFI as it has all four of those partitions. There may have been an issue with the Boot Order, or perhaps the changes I needed to make to the Bios. I wrote that the little "UEFI" icon/label wasn't showing up above the drive's icon in the Boot Order panel and it still doesn't. However, when I looked at the "Boot Override" dialog from the final screen (the one with "Save & Exit" and the other exit options) I noticed that all the drives had the UEFI icon above them. I'm not sure what is causing this discrepancy.
I wanted to list the way some of the Bios options we discussed are now set since things seem to be working. If any of these seem less than optimal or unnecessarily altered please let me know and I will go back and try updating them.

FWIW, VT-d has always been locked even though I know that the recommended setting as listed on this site for that feature is "Disabled". I don't know if there's some trick to changing that or if it even matters that much.
Congrats on the build, @flyingace!!
Glad to know you managed to do it, I know how time consuming it is, but also rewarding hehe. I have the same VT-d option listed as it is, running smooth for three years now! As far as I know, there's nothing to worry about anymore. Hope you have a great time with your new macOS
