I am going to step out on a limb here and recommend you rule out a Clark Y air foil. After that, you need to figure out desired wing loading and planned speed envelope. Wing position and C/G will determine sweep. This is not an easy question, simply asking shows there is a lot more that needs to be learned. A simple air foil type, say, one of the NACA types, is just one of many decisions pertaining to wing design. There aren't a whole lot of successful designers, when you eliminate the copycats and kit bashers. There is a reason for that.
