Anna, we have the evergreen type forest compost. It works great for my raised beds. I have never used hardwood compost, I don't think it will work.
Here is a link that sounds good. Not sure how close it is to you.

Their Growers Mix sounds great.
Marilyn it will say somewhere on the bag what kind of product the grit is. Either granite, oyster or something else. But I have had an occasional bag that was quite lite colored until it was rained on.
