Maybe try a Steam Controller? I've used the OG one. I think the device itself registers as a keyboard. Its trackpad controls the mouse cursor and the triggers act as the various mouse clicks.

If you are running Steam in the background, one of the buttons triggers an HUD keyboard, where the left trackpad types keys on the left side of the keyboard and the right trackpad for the right side of the keyboard. My guess is the new controller works the same way.

Also, some media center software, such as Kodi, have gamepad support. So a gamepad will feel completely natural to control it without having to resort to using the mouse and HUD keyboard.

There are various "air mouse" variants that properly work with MacOS as well. I have one with some media/navigation keys on the front, and a tiny keyboard on the back - kodi I can navigate just with the navigation keys, and if I want to do a bit more (but not get out the proper keyboard) I just flip it around, and can do that as well.

> I'm kind of lost on what to do with it.

Personal assistant (e.g. openclaw) in the mac ecosystem. You need external models to power it ofc, but cool to have all the Apple integration and local network in your assistant. The claw can be addressed in multiple ways and can command your local hardware if you so wish.

Sell it. Sounds like you have too many computers already and didn't need it.

I recommend a combined keyboard+trackpad device. Compact, fully featured.

You can buy a remote sized kb/mouse for 10$.
