Long time ago I did my confirmation (ex-protestant), but I seem to recall that wood is used a lot because it's a symbolism to man's mortality and frailty. Then after/with the crucifixion it also became a symbol of sacrifice and redemption in connection to mortality and frailty. But someone who remembers their studies better might offer a better explanation to why it's so popular.

Trees are big in the Torah and Bible generally. The Bible Project did a whole series on trees in the Bible. You've got the Tree of Life, the Tree of the Knowledge of Good and Evil, the cross, the tree in the book of Jonah, the fig tree, the parable of the vine and the branches, etc..

It all makes sense for a religion steeped in a desert culture. Trees are (relatively) rare, and what they offer is incredibly important and life giving.

		In Norse mythology the first man Ask was carved out of a piece of ash tree and the first woman Embla out of a piece of elm. Ash is a good choice for tool handles and elm for constructing homes.
