Hey Jay, congrats on your new purchase. To tow a trailer with brakes you're going to need a hitch, 4-way wiring harness, 7-way wiring harness, brake controller, and ball mount. I have listed these parts below that will fit your 2021 Jeep Grand Cherokee L:
Hitch - etrailer Trailer Hitch item # e39ZV
4-Way Connector - Curt T-Connector Vehicle Wiring Harness item # C27BR
7-Way Connector - 7-Way RV Upgrade Kit for Trailer Brake Controller Installation item # ETBC7L
Brake Controller - Curt Echo Wireless Brake Controller item # C51180
Ball Mount - etrailer Adjustable 2-Ball Mount item # e66PR and etrailer Hitch Receiver Lock item # e98881
Have you ever towed a trailer with brakes before and are you familiar with weight distribution hitches? I have linked an article below that explains them if you're not. That's something you may want to invest in. It'll make towing a trailer more comfortable and definitely safer.
