The original
Bluetooth SFC30 / SNES30
controllers should work if used with the
Bluetooth Retro Receiver. If you have one of these, just get the Bluetooth Retro Receiver and you are good to go.
The oddities are the 2.4GHz Controller and Retro Receiver (designed for the NES/SNES Classic Mini).
8bitdo seem to have caused some confusion by replacing the original Bluetooth controllers as shown above with new Bluetooth controllers with the same design and very similar model numbers as the 2.4GHz controllers.
SFC30 / SNES30 (pictured above, now discontinued) are Bluetooth. They will work with the Super NT with a separately purchased Bluetooth Retro Receiver (with SNES style connector).
SF30 Pro / SN30 Pro (with analog sticks) are Bluetooth and will also work with the Super NT with a separately purchased Bluetooth Retro Receiver (with SNES style connector).
SF30 2.4G / SN30 2.4G will work only with the 2.4GHz Retro Receiver (with the Wii Remote style connector) for use only with the NES/SNES Classic Mini.
SF30 Retro Set / SN30 Retro Set are the new Bluetooth controllers. They look like the 2.4G controllers but have an included Bluetooth Retro Receiver (with SNES style connector).
