Most household and building debris is fine to load. Utah's landfill rules and the county landfill's own policies set the limits.
Utah bars landfills from taking free liquids, large containers of liquid, and wet sludge. It also keeps hazardous waste and anything with PCBs out of landfills. Whole tires are banned from Utah landfills too, with a few narrow exceptions, so keep them out of your container.
The usual exclusions apply as well: no hazardous waste, liquids, paint, solvents, fuel, or asbestos.
The Salt Lake Valley Landfill adds its own rules. It won't take solar panels or battery systems at all, and it points people to a recycler instead. Paint, paint thinner, computers, and TVs go through its household hazardous waste facility, and only from residents. Mattresses and Freon appliances are charged per piece.
If anything on your list gives you pause, ask your account manager before it goes in.
