I have little experience with 4-3-3 but my default orders would be normal/attack through the middle, mixed passing, own half, hard tackling, zonal no counter no offside.

Ok maybe a 4-2-2-2 hexagon is more suited to your team?

Normal, down flanks, short passing, own half, hard tackling, zonal, no counter, offside varies. Red arrows on fullbacks only.
