The expectation is when I open the Salesforce Pane in Outlook, search for a certain Account, go to the related list and hit "New Opportunity" button, I can customize the Opportunity Creation page. What is the layout I have to update? Apparently none of the Lightning Layouts and classic Page Layouts on Opportunity object reflect the desired changes

For the layout I think you would need to go to Setup>Global Actions and look for New Opportunity and click on the Layout Link to configure the layout. Then you will have to go to Email Application Publisher Layouts. Go to Setup → Outlook Integration and Lightning Sync → Email Application Publisher Layouts and add the action there.
If you don’t see an Email Application Publisher Layout, create one and make sure the modified New Opportunity global action is included in the Publisher Actions section. If it’s not there, drag it into the section and save the layout.
I’ve added a few screenshots below for reference. I configured this some time ago and haven’t tested it recently. Also, I don’t have the side panel available in my Trailhead Playground to verify the steps. So please try and hope this helps!
