Those cables for the bay are braided steel wire and are part of the turnbuckle system that helps carry the load of the bay window as it hangs off the house. They are not used in standard vinyl (non-bay/bow) window replacement.
Oak box is an optional upgrade over birch plywood verneer. Consider also upgrading to insulated seat board. 1-1/4" plywood is not very energy efficient. This upgrade adds rigid foam board and an additional layer of plywood on the exterior sill.
Insulated in the factory is great because it speeds up the install. The only downside is if you need to install from inside as the stepped design will impede sliding the unit out. I am suprised it's not standard yet.
