Resolution Note:
When changing the background color of the ProgressBar, using the UI Toolkit debugger, you can see that the color has been updated. It doesn't show up in the Viewport of the UI Builder because the ProgressBar has a child that acts as the background.
So to change the background color of the ProgressBar, you will need to create a selector targeting the .unity-progress-bar__background uss class instead.
