Not a bad plan, just be sure your grounding electrode system is up to

That depends on what you think you'll be protecting against,
whether your utilities are overhead or below grade, where the
nearest step-down Xformer is for your little feed (usually,
~4 homes in a cluster).
It also depends on the quality of surge protector you install.
Many are just "surge protectors" in name, only.

I wouldn't worry about it. I doubt it makes much, if any difference and
I'm sure you won't see any data one way or the other. I've never seen
any surge protection experts have it enter into the discussion for how
you protect your home.
8 hours to turn off a gas supply?!?
A group of cowboys were branding some cattle.
While they were out the cook saw a sheep tied to a post. Thinking it was for that nights dinner he cooked it.
That night after dinner the cowboys were all sulking and ignoring the cook. He pulled one aside and asked, "Did I screw up the cooking?"
"No", the cowboy replied, "You cooked up the screwing."

The lightning lab at UCF in conjunction with Florida Power and Light
have done a lot testing with lightning and they have some great
Fulgurites that showed lightning penetrating 2 meters or more
underground. Safer underground? certainly but if it is a wide open
spot with nothing but sand for it to hit, that cable down there 4 or 5
feet may be pretty attractive to a bolt.
BTW in my inspecting career, the most robust lightning protection I
have ever seen in a building is for a toll booth at MM99 on I-75. It
is the only decent target for miles around, The array was more than
they put in the ground for the radio towers that are along the
Anything you do to minimize voltage spikes on your power line is a good thing...just keep in mind that the typical surge suppression device needs a good path to ground to function properly.
FWIW, most homes don't have a good ground system. You'll typically find the outdoor connection from the #6 ground wire to the ground rod is loose and/or corroded.
