Firstly, the menu item is “Paste and Match Formatting” in Word, not “Paste and Match Style”, so you’d have to tweak that separately.

Word also has quite a few settings for copy/paste behavior that will affect what it does (https://support.microsoft.com/en-us/office/control-the-forma...).

I think those vary by version. For example, Word for Mac 2019 has “Merge formatting when pasting from PowerPoint” and “Adjust formatting when pasting from Excel” checkboxes. Don’t ask me what the difference between “Merge” and “Adjust” is.

It’s a relatively late addition to ‘standard’ commands. I guess the search for an unused combo that’s reasonably logical led to different results in different applications.

I guess Apple went for option-shift-command-V (https://support.apple.com/en-us/HT201236) because it’s fairly complex, and less likely to be already taken.
