Hi All:
. I bought some brich wood for making a cab from scratch and would like to stain it to cherry wood color...
If it were me, after staining I would put an oil finish on it. My favorite is Tung oil. Three or four coats with steel wool, followed by paste wax. The finish won't be quite as shiny as polyurethane, but it will be a longer lasting finish that won't show scratches. If it gets any scuffs, you just put some more oil on it. Oil is also a very forgiving finish, because it can't run, crack, bubble, or collect dust. A lot of really fine furniture is finished with oil.
Whatever finish you go with, try it out on some scraps first. They will all change appearance as they dry. Remember that colors are more intense when they cover large areas too!
