You guys are operating at about the level of college sophomores. I think that the term 'sophomoric' is appropriate here. Cable directionality may seem 'silly' or 'over the top' but Ed Simon has actually measured it, as well has had informal listening tests with it.
There is more than one reason for 'directionality' marking on a cable. It is often also the optimum hookup to get the outside shield properly connected to a chassis. I cannot say whether a preamp chassis or a power amp chassis is best, but I would think that a phono preamp chassis would be best the cable that a phono cartridge. There are also differences in cables due to the fact that they are usually fabricated with a directional process, and which can be seen under a microscope. All I care about is what the cable sounds like. Of course, your opinion about cable differences themselves may certainly differ from mine.

You are too polite John....sophomoronic is the more appropriate term.
Cables with same connectors at each end are perfectly reversible and are useful to demonstrate cable directionality.
I recently related examples of 6.5mm guitar cable and 3.5mm-3.5mm cable causing differing sounds according to direction.
A stereo pair is similarly useful in demonstrating directional effects and reversing one channel will shift the central image sideways, and channel balance control will not cure the imbalance.

A regular rca cable has one pair of wires (per channel). If these wires are directional they should be in opposite directions, otherwise the directional effects would cancel eachother out, correct?
If the direction can be seen through a microscope, did someone verify the opposing directions?
And for XLR, with 3 wires, how do they solve this? Opposite directions for + and -, and mixed for 0?
It depends on how the cable is made. A simple coax cable has one center wire and then a shield return. Certainly they are not similar in construction. Other, more sophisticated cables use a balanced pair and a separate shield. I would presume that some manufacturers might reverse the return side of the cable to keep the directionality intact. I personally don't bother much with this, but I have known people who usually have even better sounding hi fi systems that do.
No.
Not solved.
The two signal wires will not completely cancel because of differing insulation pigments.

Oh boy, my head is quantum spin-ning! Pigments! Colour! Wavelength! Reflected light! Waves! Particles! Quantum steps! Quantum leaps! Barriers crashing down! Colours! Pigments! Waves! Energy transfer! Newton is over! Bohr is over! Physics are over! Bybee to the rescue! MOMMY IT HURTS!!

It probably is a zobel network but putting a random zobel before the crossover is brave. Hopefully the box is empty, that way it would cause the least harm.

Audiophilia Compulsive Disorder is a form of Obsessive Compulsive Disorder in which the sufferer is convinced that there is something fundamentally wrong with the components of their audio system down to sub-atomic levels and they feel compelled to do something about it, endlessly chasing non-existent problems to the point of insanity.
Okay, so since almost all cables use multi-stranded conductors why don't they just put half the strands one way and half the strands the other way?
I'll tell you why. Because YouTube
