My Wii has GameCube controller ports, and I use the controllers that I linked below. They’re a little “clicky”, and stiff, but they do the job and I didn’t notice any input lag.

I have used the adapter linked below that to use the same controllers on a Switch. This set-up will also work on a Wii U.

The link below that is in case you need cable extensions. I did.
