There are the 3 colors of PEX and I don't know if there are differences in the different colors such as the red for hot water or if it is simply color coding. Some of the problems with PEX seems to be in the older and cheaper fittings. Here is an interesting read: https://www.pexuniverse.com/problems-pex-pipe-and-how-prevent-and-fix-them

White, red and blue is just color coding. Then there's the oxygen barrier stuff for radiant heating which IIRC is orange.

I've heard of some issue with older brass fittings but the only problems I've personally seen have been with the cheap plastic fittings.

We always ran galvanized airlines back when service stations were actually around. Ive run tons of it, never had an issue. I have black iron in my shop because I had a stick of 3/4 from some job. It only goes to my air reel, shop is small enough I don't need much piping with a 50 ft reel ;)
