Optimal cable thickness?

As cable gets thicker its resistance drops, but its capacitance would rise. Assuming size and flexibility are not an issue. I wonder if there is any established optimal thickness for cable from the audio perspective? Both for signal (interconnect) and amplified signal (speaker or headphone cable).

Just large enough to support the amount of current that will be flowing through it without burning up.

I find 16 or 18 gauge wire to be perfect. Not too big, not too small.

There are always trade-offs. Another example is star quad versus twisted pair geometries. Star quad is more immune to EMI and RFI, but its capacitance is significantly higher than twisted pair. I've found that it's best to look for wire suitable to your specific cable type (ex. RCA, XLR, TRS, TS, etc.) and purpose.
