Are you asking for something that fits in a single gang box? Your drawing seems to imply a triple gang width for the spot where the fan Switch is.
If you’re asking for a multibutton device that controls multiple circuit branches, there really isn’t anything that matches your requirements. They’re all “remotes” or “scene controllers,” which means they just send a command to the hub and then the hub sends the command to some other smart device which controls the actual circuit branch. That would be very different than your drawing.
There are certainly multibutton wall units, but not multibutton wall units that directly control multiple branches. And they don’t do dimming, so you have to create set scenes for the different dim level combinations that you want.
So are you asking for something that goes in a triple gang box next to the 2 GE switches you have indicated? That could work as long as you also put an in wall micro or smart bulbs where your recessed lights are.
Or are you asking for something with the same functionality as the GE switches but with everything to fit in a single gang box?
