GSMARENA Phone Finder is pretty amazing. You can filter by basically any phone characteristic you want. Back material? Yep. Refresh rate? Also yes. Proximity sensor? You got it. Minimum wired charging wattage? Sure, why not.
I’ve yet to find a more comprehensive one.
Edit: taking a look at Kimovil. It seems like it has much of the same filters as Phone Finder, but with the bonus of also showing price, which is nice.
