Only obvious benefit is, if I need to use my laptop in another office, it’s a lot more convenient to have the Windows 10 image on my internal disk, so I do that. I’ve run Windows on my 1TB SSD and on my internal SSD in Parallels. Parallels? Feels like I’m running Windows natively, no lockups, does Windows Updates normally, when I move off of Parallels to Mac apps - CPU is reasonable and fan isn’t running. There would be long periods of lockups and CPU usage would always be high with the fan running. I could never get VMWare fusion to work right, even on the internal SSD. Parallels allowed me to use my Windows 10 copy on my Mac as if it ran normally, without high CPU usage, so much so that I’ve ended up using my MBP at work now for the last week. I switched to Parallels because VMWare fusion would result in a Windows 10 that locked up and never recovered during updates. I haven't tried turning any of the boot security features back on yet.

Real quick and dirty guide here, let me know if anything needs any further explanation.

After a couple of reboots, you should be able to use your internal mac keyboard/mouse at that point.

Once Windows is installed, run the setup program for the Windows Setup Files (step 2, 5) to install the drivers.

Select a 'custom' install when windows setup asks, and format the X5 with NTFS (don't touch the small EFI partition)

Also make sure you have a USB Keyboard and mouse connected as well.

Make sure your X5 TB3 drive is also connected.

Reboot your Mac, holding down option key, boot from the USB key.

Turn off all boot security and select the option that allows booting from USB.

Boot your Mac in to recovery (hold command+r at boot time), in the utilities menu, select the startup security utility.

Boot back in to your Mac and put the Windows Setup files you downloaded in step 2 on the USB key.

Borrow a working Windows machine, use Rufus to write the Windows 10 ISO of your choice to the USB key.

Get a USB key with enough space for the ISO.

Load BootCamp in MacOS, under one of the menus you'll have an option to download Windows Setup files (drivers).

Format your X5 in MacOS FAT32 with a GUID partition table.

Note: Windows 10 typically doesn't allow you to install to an external USB, however if it's a true TB3 drive, it sees it as an installable drive. It wasn't too bad, here are my quick tips:
