Spotlight finds Word Docs, but shows them with a Finder icon and won't allow me to open them by double clicking in spotlight window

Title says most of it.

Here's what happens:

• • I access Spotlight from the menu bar with command-space
  • I perform a spotlight search of the form textstring kind:word
  • I get results, but each Word file is shown with a Finder icon instead of a Word icon.
  • I double click on a file shown in the Spotlight results window, and it does not open.

Here's what I've tried to fix it:

• • Reindexed the drive I am searching by dragging it to the do not search window and then removing it from the do not search window in the Siri and Spotlight pane of System Settings. This didn't seem to help.
  • Using "Get Info" on a Word file to set "Open with" to Microsoft Word and apply to all documents like this one. This seemed to partially work. Some but not all Word files now show up with a preview view as their icon, and I can open these by double clicking on them in the Spotlight window. Others, though, still have Finder icons and I can't open those.

I am running Ventura 13.2.1 on a MacBook Pro (13 inch, M1, 2020)

Thanks for your suggestions.
