A lot of the balloon use has switched to nitrogen (helium became much, much more expensive after the strategic helium reserve was sold off)

Nitrogen? That's basically just air, what good would a balloon be using nitrogen? Might as well just blow it up with your lungs. It's certainly not going to float in any case.

More than just from inflation? (sorry, not sorry!)
Is lifting gas? That’s pretty cool.
Technically yes, but practically no. Air is 78% nitrogen. Nitrogen is 3.3% lighter than air. Helium is 86.2% lighter than air. Hydrogen is 93% lighter than air.
How much does that matter for party balloons, though? It's still buoyant.
