Long ago, I was taught that the route of lightning was normally wingtip to wingtip or nose to tail. My first three strikes mystified me when I could find the entry point but not the exit. Turned out that it went nose to wingtip on all three (2 on Cessna 400 series and third on Bac1-11).
Have had many flying around the tropics in 747s of all types without major damage - a few welded rivets, holes in GRP panels etc.
Grounding is now so good that there is often little to tell. Certainly in the modern glass jets, a compass check is a bit superfluous since, with the excption of the standby compass, all magnetic displays are generated by computer from the true track data from the IRS.
Biggest gotcha can be if the radar stops working - could have blown your radome off. Happened to a VC10 out of east coast USA many years ago and he barely made Shannondue extra fuel burn. Check those fuel flows!
