I was on a Jazz CRJ a few years ago that was struck by lightning. We were pretty far into our descent to Pearson when we were hit. There was a loud bang and a bolt of lightning (or a flash, at least) went right down the middle of the aisle followed by an acrid smell. One passenger freaked out but the rest of us just looked on calmly. Once at the gate, it took them a long time to get the cargo door shut as it had been welded shut, or so they said. In those days, they still had gate checked bags so we had to wait to retrieve them.

I wasn’t too worried as no aircraft functions seemed to be affected and we landed normally, but once on the ground and having to wait for maintenance it made me wonder what would have happened if one of engines had been hit instead.
