As a general statement, more camber generates more lateral force. You need the characteristics of YOUR tires to know what the gain is. While you may imagine that the center of vertical load is in the center of the wheel, it is most likely not. As a result, there is an offsetting moment (Mx) which is this lateral distance times the net Fz (vertical) force. You can see this in videos of tires being tested and from cameras watching tire tread movement while cornering. If your car has "roll-camber" compliance (camber due to roll), it also responds to this moment by increasing the body roll angle (generally by about 10%).
Even though you hear all the blather about scrub radius needed for braking/traction stability, the Mx gets involved with what is called "pneumatic scrub" which can increase OR decrease the static scrub radius, even to the point that it can change the sign. Very important in FWD cars because this effect has been found to be tire brand dependent, and if the effective scrub radius goes positive, you will have your hands full when this sign change occurs while going with throttle up.
If it's max-lat improvements you are looking for, the goal is usually to keep Mx to a minimum in order to maximize the full tread patch contact pressure.
Here's the caveat: Just like "optimizing" Ackermann turning geometry for the pair of front steered tires, if you don't also improve the rear lateral capability, your car looses understeer and will loosen up, to the point where it's unstable without massive timely corrections. Anti-Ackermann (more toe-in with steer) can greatly improve front lateral grip, but can kill the car because the rear can't keep up. So it gets a black eye. This ALSO depends on the tire properties because it takes advantage of the slip angle at peak Fy location increasing with load. Not all tires do this. Some have their slip angle at peak Fy decrease with load, so you need +Ackermann (toe-out with steering) to gain an advantage.
Search for "Tire Force & Moment Properties" literature. Not a lot of specific facts usually, but a huge diet of bullshit awaits you !
