I also recently tried chicago95, it seems to have some issues with the latest Xfce version, so if you see your notification area icons have squares around them, there is a workaround on the GitHub issues page of the project.

When I used the workaround, the taskbar lost its 3D border effect, so I recovered that by using a background image that is 1 pixel wide and has the correct colors to have the 3D effect. It’s better if you use something like Xubuntu 22.04 first to see how it should look like without this bug.
