I'm afraid that sleep for the Z420 has been broken since High Sierra. You'd need to stay on Sierra if you need working sleep. USB 3.0 can be partially enabled via the GenericUSBXHCI.kext but the system doesn't fully recognize the controller so USB can't be properly mapped. A third party USB 3.0 PCI card with an internal header for your front panel USB 3.0 connector is your best bet. Finally, audio is fully functional with the correct layout id. You can search for joepool's repository on Github for more info. Good luck!
