I run Helium in my truck tires. Now I have to carry ballast to keep it on the road.

The last time I ran helium in my tires, they sounded funny.

My car apparently got nitrogen fill at the dealership with purchase. They used metal caps, a no-no with the metal typically used in TPMS valve stems. One got corroded on to the point where I had to use a plier on it. In extreme cases the stem can be broken. So use plastic caps only.

We have nitrogen tanks for pressure testing A/C systems.
If I get stuck on a lube oil change and have to fill all the tires to 120 psi I grab the nitrogen tank or you'll be all day using shop air for 10 tires.

When I had new tires installed at Costco they put in nitrogen. 35,000 miles and a couple of summer/winter transitions and I have not had to add anything to the tires. On our other car I have to add air at first big cold snap. YMMV.

Don’t forget the non OEM flush services…..

Regular air is already 78% nitrogen.

In central Florida during the winter months it can get very cold overnight, for Florida. I walk my wife out to the car every morning when she leaves for work.

Costcos with tire centers have a free Nitrogen air pump outside, pull up, set the pressure and it auto fills, these don't get the abuse of the normal air compressor fill stations. So hit Costco for Nitrogen

Yes you can mix in air but if you haven't done that to keep it 100% nitrogen then Costco is your best bet.
