Different category page changes for 1 column and 2 column pages

I have a site that uses 1 column and 2 column layouts for category pages (some pages are 1 column, others are 2 column)

I made a change to the catalog_category_view.xml to update the layout of the 1 column pages, but it didn’t have the intended effect on the 2 column layout pages. I need to make a different change to 2 column layouts, while keeping the changes I made to the 1 column layout. I don’t know how to do this inside of 1 catalog_category_view.xml file, or if that is even the correct way to handle this.

What is the proper way to change the layout for only category pages with there being different changes required for 1 and 2 column layouts?
