Sealing attic - What type of foam/sealant to use

Can someone answer what portions of attic sealing need firestop caulking/foam and what areas are fine for standard expanding foam. Most videos you see about attic sealing are using foam that looks like Great Stuff all over. I've seen video demonstrations showing how Great Stuff burns and will keep burning (even Great Stuff Fireblock), whereas something like Abesco FP200 resists burning.

Any thoughts from someone knowledgeable on this.
