For your needs any symetrical airfoil of the right thickness would be just fine. Especially if you will be including the use of functional flaps for takeoff and landing.

I would include the slight anhedral since it does add something to the model when seen on the ground and in flight. Aerodynamically it won't make a bit of difference due to being so slight an amount.

And DO include the wing fences. It was the Mig's way of controlling the span wise airflow and including them should reduce the need for washout in the wing tips. However I would still include a couple of degrees of washout. Swept wings can do funny things near the stall without such tricks.
