I'm on Arch with Linux 6.3.8 and GNOME 44.2
All the ones I'm using right now are:
- AppIndicator and KStatusNotifierItem Support
- Blur my Shell
- Dash to Dock
- Overview background
- Pano clipboard manager
- Material You Color Theming
- Night Theme Switcher
- Rounded Window Corners
- Transparent Window Moving
I'm using Material You color theming to get colors from my dark and light wallpapers, but you can also use Gradience with adw-gtk3 for a more manual approach.
