Monopoly framing + exterior insulation + overhangs. How best to wildfire proof?

A homeowner planning a new house in a moderate wildfire risk area raised a question worth passing along to anyone building or remodeling in fire-prone country: how do you protect against wind-driven embers, which are one of the main ways homes catch fire during wildfires?

The house in question uses a wall and roof design built almost entirely from non-combustible materials: fiber cement or metal siding, mineral wool (rockwool) insulation on the outside of the wall, and a water-resistant barrier under that, all over standard wood framing. Everything outside that barrier is fire-resistant, with one exception: roof overhangs, which normally need wood framing to stick out from the wall. The question is whether there's a way to build overhangs without introducing combustible wood, or whether the safer path is to just use a fire-resistant wood species instead, alongside ember-blocking screens and vents at the soffit (the underside of the overhang) and roof ridge.

For homeowners in wildfire zones, the takeaway is that overhangs and eaves are a known weak point in an otherwise fire-hardened design, since embers can collect and ignite materials tucked under a roof edge. If you're building or renovating in a fire-prone area, it's worth asking your designer or builder how the eaves, soffits, and vents on your own house are detailed, since these details matter as much as the wall assembly itself when it comes to ember resistance.
