Why do we limit ourself to cross -> f2l?

Specific to cfop if it isnt already clear

Why dont we just blockbuild the majority of the first 2 layers? That would likely be much more efficient. Im not talking just xcross, why dont we just completely ignore the idea of bottom edges (cross) first and do whatever is most efficient first?

its used in fmc where you reach f2l -1, but it does require lots of thinking as alex said

That's called FreeFOP

Most of the time it isn't optimal for speedsolving because it requires more thinking. Traditional Cross+F2L is much easier to lookahead
Actually, it is often optimal for speedsolving (from the opinion of a Roux, Cfop, & FreeFOP Solver) most of the times it is honestly better to do block-building in situations rather than just a traditional cross+f2l, this, of course, is determined by your speed at 3x3 in the first place, depending on how much you practice your block building, FreeFOP can often be more Optimal than traditional CFOP Cross+F2L, and for some people thinking ahead isn't an issue with the 15 seconds of inspection, and lookahead really isn't an issue with FreeFOP in my experience.

“Optimal... from the opinion of...” those two cannot coexist in the same statement. To say something is optimal it needs to be determined for every case via some objective software to compare things like move efficiency for example.
The main reason block building isn’t done as much is because 1. Cross eliminates D layer edge blind spots, and 2. Thinking and block building is usually slower than recognizing an F2L case and then spam TPSing a solution.

The original prospect of this thread is strange. We are not LIMITING ourselves to solving cross and then F2L when using CFOP...that is just the direct application of the method. One could definitely use other techniques to start the solve but then they wouldn’t be using CFOP!

The method is just a construct of ideas and of rules that always applies. By all means other things can be done but once the “rules” are modified it’s no longer directly CFOP. Keep in mind the knowledge of a method is merely the framework for your solve not a strict contract you must abide by.

I think the real question is why do we CFOP solvers limit out selves to CFOP? Well, learning multiple methods is hard and many aren’t up to it.
