I did, however, find yet another instance of com.apple.finder.plist in [HardDrive]/System/Library/Preferences/Logging/Subsystems, and interestingly, THIS instance was not found by EasyFind. I found it by digging through folders. System won't let me delete this instance.

EasyFind found it for me. Might be where you told it to look. Has to be at "/".

Enter in user library macOS Sierra: Library folder

Find a folder preferences - you can view finder plist , avoid using easy find app , if the issue still exists in the test user account , its better to always erase the hard drive and reinstall os .

I haven't seen this issue before in these forums. Usually it's a problem that either affects the User folder or the system, but not both. Yet the steps you took indicate it affects both. It could be a failing hard drive.

Do you have a Time Machine backup or a clone you can use to revert to your previous system? If not, I'd try doing a clean install on an external disk and booting from that. If it works as expected use Migration Assistant to migrate your files and clone onto your internal disk.
