Brazilian Rosewood.
The most expensive would be those not legally available anymore - i.e. Brazilian Rosewood. Otherwise it'd be woods with exceptionally rare figure (grain pattern) like Ebony Burl. Also what drives price up is size of board: a 5-foot wide Padauk board can cost $5k easily. The wider & longer, the more money.

Not necessarily, as it all depends on the type of wood you are interested in purchasing. Most "pine furniture" is very inexpensive, especially if the wood is unfinished on the surface.
A shed can be made out of almost any wood. Most are softwoods so the most expensive will be well seasoned fine grained softwood. Of course, there is nothing to stop you building a shed with hardwood. It's slower growing so they are far more expensive than most softwoods. Lumber such as oak would be a fine choice as it needs no preservatives and will last for many years. It is unlikely that there will be a more hard wearing wood than oak so that is probably going to be the most expensive wood that is still a sensible choice.
What ever wood works! In most cases they will use the least expensive wood available that will make the appropriate strength boxes.
