Plug it, and patch it on the inside and forget it. The reason they do
both is so it cuts down water/dirt separating the plies in the hole,
the patch is to hold the air and backup the plug. There are also some
special plug/patches out there that have a head on them like the
inside patch. Then again if you're racing it all bets are off. My
right rear has a plug in it that has worked well for 2 years, non
runflat rain tire.
Don't do this if the screw is anywhere near the sidewall. I did this
and it all came apart in the fast lane with the slow lane nose to
tail. A bit embarrassing. Plugging inside the tread pattern has
worked OK on many occasions.
I think this says about the same thing as my
tire guy. For runflats he only plugs in the
mid-2/3 of the treadwidth.

If you limit speed to where you can maintain
control and get it stopped before disintegration
tears up bodywork then it doesn't matter.
