Comment on Other than a faulty charging port, is there any reason to use a wireless phone charger over wired?

it shouldn’t.
There shouldn’t be any heat at all from the signal passing through the plastic (It’s basically transparent to RF’s,). The heat mostly comes from the RF interacting with the metal in the receiving antenna and inducing an electric current.

The extra space isn’t going to cause more heat on its own, but the phone is still going to get warm, and a thick case can prevent that heat from dissipating properly. A good charging design will already have taken this into account, and start limiting current if the temp gets too high.
The primary downside to using induction charging through a case is decreased power transfer efficiency due to the greater distance.

The case prevents the heat from the phone (which should be the same) from dissipating so it can possibly build.

Although most phones made in the past decade will detect that, and suspend wireless (and possibly wired) charging if the phone’s circuits are heating, until the temperature drops.
