The parts you're looking at getting for your 2022 Ford F-150 are definitely on point with what I would be recommending. I recommend picking up the Demco SBS Stay-IN-Play DUO # SM99251 and the Brake-Lite Relay Kit # RM-88400 (so your lights work correctly) because it installs one time on your truck and then remains out of the way when you're driving your F-150 normally. The Stay-IN-Play DUO is also known for it's performance and accuracy with braking so you can be confident your F-150 will tow like a dream.
The only other changes I would make is using a high-low adapter (see below) and swapping the wiring kit to the Towing Combo Kit # RM-9284-2 because it has the diodes and wiring but also a cover and locking hitch pin to help secure your tow bar and protect it from the elements. So going with these new parts this is the list you're looking at:
Nighthawk All Terrain Tow Bar - # RM-676
Direct-Connect Base Plate Kit - # RM38VR
Towing Combo Kit - # RM-9284-2
Demco SBS Stay-IN-Play DUO - # SM99251 OR # DM86VR with wireless monitor
Brake-Lite Relay Kit - # RM-88400
Motorhome Charge Line Kit - # RM-156-75
Towed Vehicle Charge Line Kit - # RM-156-25
High-Low Adapter - See Attached Article - Base plate kit has 15-1/2" height
Some people also like adding a protector like the Roadmaster Tow Defender # RM-4750 to help prevent road debris from hitting their towed vehicle but it's more of a preference.
I've attached some review videos for you to check out as well.
