Just like ancient people on Earth used every part of the animal we can use every part of trees to make sure nothing goes to waste. I am not sure what the developers have thought when it came to how trees can be used besides as building materials and firewood so here are my two cents.

I like the way you're thinking! A couple thoughts:
Charcoal has a clear use in crafting- most coal has too much sulfur for steelmaking unless it's coked, and humans didn't figure out how to do that until relatively recently. Most medieval steelmaking used charcoal (which had the side effect of deforesting a good chunk of Europe). I would love it if distinctions like this mattered in CoE.
Cork is a specific kind of bark, from a type of oak. It's one of the few tree products that can be produced without killing the tree, and obviously it's incredibly useful!
Something that you didn't mention is "tapping" trees for sugary sap, like birch or maple are tapped in wintertime and the juice boiled down to make syrup.
