The best 5th wheel hitch for your 2021 Sierra 3500 with prep package is Reese M5 5th Wheel Trailer Hitch for Chevy/GMC Towing Prep Package - Single Jaw - 27,000 lbs # RP58FR. This hitch has a superior jaw-to-king-pin design that is always ready to receive so you don't have to open the hitch prior to hooking up the trailer. This also has a fully articulating head and built-in shock dampening for a smooth and easy ride.
This is compatible with the Reese Sidewinder # RP34FR when also using the Wedge # RP44FR.
