A family of Microsoft word processing software products for creating web, email, and print documents.
As Stefan replied, those options do not exist in Mac Word. They were not eliminated, they never were included. The only Paste Options Preferences pertain to pasting/inserting pictures which provide for choosing a default Text Wrap style. The default behavior is determined at the design level & may have been changed in response to Feedback submitted by users.
On a different plane, there are Preferences in Word> Preferences> Edit which provide Settings for the Smart Cut & Paste function. Although you may find them useful I doubt they are what you are looking for.
In Mac Word keyboard shortcuts are assigned to several paste options & you can assign keyboard shortcuts to the others as well as some which are lesser known. For example, I have assigned Control+Option+V to the PasteSourceFormatting command & Shift+Command+V is assigned by default to PasteTextOnly.
