I've had setups that involved all of those you listed. I experimented with a simple IGO-L with 1Ω 1/16" "micro coil" and using non-boiled, sterile cotton roll gauze i didn't see too much of a difference to tell you the truth. As long as i didn't completely cover the coil i didn't have problems. That said there are a few things to take into account. Do you want to drip more/less often... how deep is your well or deck... how thick is your juice... etc. I personally would do as i did and make a simple coil then experiment with different cotton setups with the same juice. Preferably one you're familiar with. Drip enough juice so you don't burn the cotton take a few vapes then pull er out, rinse under water and dry burn the coil... repeat.
That all said i my personal preference for an RDA while concentrating on flavor (no cloud chaser here) is...
Start with a long piece of cotton (you can always trim, you can't add more) make sure the overall piece is not too thick as you want it to have room to expand inside the coil... roll one end pull through and trim the mashed down "tip"... use that ~1/2" end left and bring around under the coil... it should fit under easy and shouldn't be packed and it should stretch under that coil and make contact with the other side of the wick making a little loop. Take that other end of the wick and cut enough to allow for one light and airy trail around the deck to the other side of the posts.
I posted this earlier today but this is my go to cotton RDA setup... hard to see all i described but it there lol. Again, the entire length of the wick is very light and airy and that helps absorption and wicking of the juice. This is all just what i like to do.
