The urge to smelt: current items that could be used as fuel

I find myself while playing in my survival worlds accumulating many different items and (lets be honest) hording an absurd amount of them. I have thought about how to deal with a lot of these items and how to put them to use instead of having them sit around in a chest somewhere. I realized that a good way to recycle these items could be to use them as fuel for massive smelting/cooking projects.

My proposal is this: there are many items which I would assume should be able to be used as fuel in my furnaces. The list of items that I cannot burn, but I really want to are listed below:

wheat (item), Hay bale (block), shield, paper/maps (any), lead, arrow (basic version), books (item), any seeds (wheat, beetroot, melon, etc.), feather, cocoa beans, name tag, string, sugar cane, leaves (block), cobweb, bed, hanging roots, item frame, mangrove roots.
