8BitDo Ultimate 2 Bluetooth Controller for Switch/Switch 2 & Windows PC has now been updated for the Switch 2, so works the same as the Switch 2 Pro controller, including back buttons (the wake from sleep function of the Switch 2 Pro controller has yet to be updated on this though)
To me, a much better but than the Switch 2 Pro, as it has Hall effect joysticks, more buttons, and can work on other devices (the Switch 2 Pro controller only works on Switch 2)
