Getting close to the walls to be fast isn't an aerodynamic effect, it's making the track as wide as possible and thus being able to carry more speed though the apex.
What I mean is what effect does getting close to the wall have on the aero of the car itself. If ground effect works better the closer you get to the ground(to a point), out wash will work harder the closer you get to the wall(to a point)?
No it won't. They are different effects. The point of the outwash is to move the dirty air (front tyre wake) away from the car to the side. If you move a car close to a wall then that air has nowhere to go so you'll probably start to lose downforce as it means the dirty air will be forced to interact with the floor and other elements further down the car.
That's why drivers say they lose so much performance when driving next to other cars and one of the things making overtaking harder. The simplified front wings for 2019 was an effort to partially fix this.
How are they different, if you a confine a non compressible fluid it speeds up to a point. Aero works regardless of your orientation, in 3d space.
Furthermore cars lose downforce driving behind, not next to cars. 2019 rules just ended up costing teams money. They failed in their objective pretty spectacularly, and I would feel shame using that as an example of a well thought out rule change.
