A couple years ago, my neighbors house took a DIRECT HIT by lightning!
I was standing in my kitchen, and saw it out my window! I went outside in the pouring rain to have a look. I could see a hole in their shingles, and a few pieces of their shingles were laying on my back patio, still smoldering!!!
EVERYTHING ELECTRONIC in their hours was toasted. Fridge, washer, drier, TV, etc, if it was plugged into an outlet, it was toast!
Power flashed off/on in my house, and all my gear was plugged in (through a cheap surge protector)! I got danged lucky! The only thing that toasted of mine was my aging Dell Tower PC that I was already considering replacing, gave me a good excuse to upgrade.
But yeah, when I'm at home and a storm rolls through, I typically unplug everything.
