Yep agree that a NACA 2315 would be good. Or you could thin it slightly and go with a 2312.
Or for easy building you could use this Randy Randolph style airfoil that has a flat lower rear portion which fits neatly on the building board. As long as you can keep the weight from going out of control these will likely work as well as anything. Particularly if the wing will be open framing with film covering where the airfoil becomes distorted between the ribs anyway.

My go-to 'semi' is the Selig S8036 as used by Top Flite on their P-47.
Thick & strong & behaves great at low speed, works well with flaps.
I even used it on my first turbine model (own designed) which amazes
people with it's slow approach & landing speeds. It's a bit draggy for a
fast jet model though. - John.
