If you have not towed a trailer before, doing so for the first time, with all your possessions sounds like a terrible idea.

We moved from MN to AZ and back a few years later using U-Haul. We towed our vehicle. But I grew up towing trailers. If you didn’t and don’t have some experience towing, I would suggest finding another way.

Driving a U-haul without a trailer, while challenging for people that don’t have much “truck driving” experience, is doable by most drivers.

Flying / bus back and driving your car separate as mentioned is a great idea.
