It looks like Panasonic has a 80-100cfm fan or fan/light that’s 3 3/8 deep. Really good exhaust fans but if you’re going to wire one in you need a good grasp on electrical. 120v constant hot gets fed into the fan, low voltage switch loop to the switch on all the ones I’ve used.

Worst case if you have a firm 3” restriction you could fir down the opening with some s4s trim.

I heard Panasonic ones are more expensive. Tomorrow I'm getting an 100CFM inline duct fan and grille and try it out first. I have recently moved a thermostat across a few studs, but I haven't added switch + fixture before. I watched a video yesterday and will watch again and take notes so I don't mess up the electric.
