None that I am aware of, none of those building elements get hot enough to worry about proximity to insulation.

On a side note, they make light fixture boxes that you can put right next to insulation, they are called IC for Insulation Contact.

+1 on the light cans

None that I know of but I am sure that GBR will have a link.

I wouldn't worry about a properly shielded electrical wire or normal temperature (residential) hot water pipe.

Fiberglass batt is what is inside wood stoves

The kraft paper however WILL burn, but not against a hot water pipe or even steam pipe.

The 3" is for recessed lighting. A normal hex box with a fixture doesn't require blocking. A 1970s can light would unless it's listed for direct contact as mentioned above.
