what you need, in addition to surge protection at the electrical device, is a whole house surge protector. It will stop the lightning strike immediately. Mine was 120.00USD plus 75.00 to install. totally worth it. These are used in place of lighting rods.
I got one of these mounted to panel, and have avoided all problems since then. Easy to install to the power distribution panel, relatively inexpensive, and no maintenance.
