Hi, I know a bigger ratio in a frontwing improves glide and reduces the lift , but I think we all suppose that all big ratio foils are thinner, which is also good for glide but could not be always the case.
On the other hand, two foils with the same lenght and thickness but one with more cord than the other, the wider would have better lift but worse glide?

I'm having a bit of a hard time understanding exactly what dims you are looking at?
I know measurements for foils as:
Span
Chord
Thickness
Area
Aspect ratio

Roughly speaking yes, but you need to factor in speed. You could have the opposite result at high speed or low speed depending on the foil profile chosen (which may still be the same thickness).
The foil profile (like camber) is also a design characteristic influencing the glide.
Glide itself does not have 1 definition. Some wings can maintain flight at lower speeds longer (low stall speed), others have less drag but higher stall speed. I think "WakeThief" used to test for glide by stopping to pump and measure the distance between the last pump and contact with the water surface.
Foils continue to work when your board touches the water. A smoother entry makes it easier to regain enough forward momentum to fly again. A stalling foil requires more forward momentum.
