Facebook offers a lot for sale as well today. It is amazing how many people do not know that what they have is not solid wood. I have seen pieces that I was tempted to buy even though my house is too full of furniture. Plain sawn oak is fine, for flooring it is not the prettiest wood on its own. My furniture tends to be most maple with a bit of pine, cherry, oak, and ash. I am sure there is some birch in there too. I have one table top that is red oak with a faux quartersawn top. The top is constructed of boards with a 1 inch height and width that were oriented so that it looks as if it were quartersawn.
If you buy something if you know the manufacturer you can sometimes look up and see what woods they worked in. Pieces called "maple" are often birch. Especially chairs since it steam bends far better than maple does. The same applies to many "oak" chairs. They are quite often ash, especially when made in New England. Ash steam beds much more easily and though open grained it is not nearly as clunky as red oak. Many people are unfamiliar with white ash, just remember, it is the traditional wood for baseball bats. Hard rock maple is a recent innovation in bat material. One can turn far more delicate spindles out of white ash than out of red oak. Some woods scream "veneer" which would be on mdf if it is from the 1950's or later. Pecan for example. It is more of a southern wood and the plants in the south tended to do more veneer work. Veneers allow more creativity, but I am not a fan of medium density fiberboard. No one tends to veneer on solid wood these days. You can find antiques that were done that way. But nothing close to be new is made that way any longer. Lastly for most people "cherry" is a color and not a wood. Cherry is usually stained because natural cherry will darken a bit on its own. And if one has something on it that blocks light that part will not darken. One has to be aware of that.
