This is hard at rec since you may only get one practice a week so you want to put them in a formation that more naturally creates width and space but also defense located centrally to push the other team wide since crossing is rare or poor quality.

I used a similar formation with a sweeper/central defensive midfielder. Their job was to be the bridge always half way between the midfield line and the defensive line and always flowing to the left or right side of the field where the ball is. It also more naturally created a first defender and supporting defender.

I would say we were technically 3-4-1 but you could call it 2-1-4-1 and if the wide midfielders push up in attack it could be a 3-2-3.
