Hi @ Michael
Some of your requirements can be achieved through group policy or registry keys, but users can still change the most of these settings later.
Word 365 > Options > General > uncheck Enable Modern Comments
In the registry editor, locate to HKEY_CURRENT_USER\SOFTWARE\Microsoft\Office\16.0\Word\Options
, find "DisableModernComments" value.
To disable Modern Comments, this registry value is decimal "16026" or hexadecimal "0x00003e9a".
Word 365 > Options > Advanced > uncheck Use Advanced Typography
Currently, I have only found solutions for manual operation through the UI interface.
Word 365 > Options > Save > uncheck Autosave files store in the cloud by default
You may edit group policy: User Configuration > Administrative Templates > Microsoft Office 2016 > AutoSave > Enable "Turn AutoSave by default in Word".
Change the Ribbon to classic
For Ribbon UI, you may export and import Customize the .exportedUI file. OR you may use .xml and VBA to customize the ribbon. The reference: https://learn.microsoft.com/en-us/previous-versions/office/developer/office-2010/ee767705(v=office.14)?redirectedfrom=MSDN
OneNote: Change to Horizon tabs
Locate to Computer\HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\OneNote\Options\Other
in Registry Editor, find the value of "VerticalTabLayoutState", when its value data is "0", it means "Horizonal Tabs" layout is enabled.
OneNote: Options > Display > Move Page list to the left
Via group policy: Administrative Templates > Microsoft OneNote 2016 > OneNote Options > Display, enable "Page tabs appear on the left".
