I'll just let you imagine I've done a big tedious Beer Bore post about whether Americans 'win' at craft beer and that this is you already having scrolled past it.

I don't know if I've ever had proper American cheese but a quesadilla recipe from that Babish fella popped up my Youtube recommendations and he was talking about using Monterey Jack because it ends up with a mozzarella-esque stretchiness once it's melted. But if that's the selling point there surely you'd just mozzarella? Though I suppose that's pricier and if you're bunging it in with actual cheddar as he did maybe it makes less of a difference.
