3-way switches

I believe I understand the concept of 3way, at least in the manner I want to run this.

Power source > 14/2 to the first (3-way)switch A > 14/3 to the second (3-way) switch B > 14/2 to the light. Should work the way I want. And if I want more lights I’d just run a series of lights after the light I mentioned above. (Let’s just say 4 lights total)

If I do this, both switches should operate the 4 lights in the manner I am expecting them to.

I have 3 sets of 4 lights I’d like to do this to. And if my maths are correct, it should be under 80% of the 15 amp circuit.

So I don’t want 3 switches on the wall where the A switch is. I want to just put 1 switch and have it control all 3 sets of lights. Shit I just figured out that I can’t do what I want, but I’m gonna keep asking my question just in case.

Is there a way to control all 3 sets of lights but still have the far switch work or will it end up being a case where I have to go make sure all the other switches are toggled the same way anyway?

Would it be silly to have a regular switch prior to the switch A to just turn all of them off?

Any input would be awesome. Thanks everyone.
