Figured it out. The WHERE condition apparently needed to come before the ORDER BY. The following query worked:
<td>[gdoc key="https://docs.google.com/spreadsheets/d/11o6a-sH57Nr1qhLYDGq0PFWrMIkuGpG3YcwMfTkK59s/edit?usp=sharing" gid="1558689791" class="no-datatables" query="SELECT C, I WHERE F = 'ALL' ORDER BY I DESC LIMIT 3" ]</td>
Thanks, Tim. I was able to make my desired changes in no time. Glad you liked how I’m using your theme, which is of such great quality. Again, much thanks.
Thanks for following up!

You’ll notice that I’ve already edited the CSS to change the default link, footer and toggle menu colors.
