Chicago95 is nice, but these days you should also install the (experimental) GTK+4 theme from b00merang https://github.com/B00merang-Project/Windows-95 https://github.com/B00merang-Project/Windows-95 to get proper styling in the latest apps. That repo also has configs for Cinnamon, GNOME-Shell and MATE desktops in addition to the Xfce which Chicago95 also provides. (Unfortunately it has not been updated for some time, whereas Chicago95 is more up to date.)
