I only know a few people who use the classic CC, but I do know more people who even their own spread or uses others spread. I know a professional who uses 3 cards, but she does the past, present , and future. Another friend of mine does the horseshoe spread. I personally use 3 cards and read whatever way I want to since I do not use any spread or position whatsoever.
I like to read the 2nd card first and see what I can get from that then I move on to the first card and after that the 3 card. I also try to find what each card has in common.
Example of one of my querent
My querent told me nothing about himself and just wanted to get a reading to see what I can see for him. I used my Ghost & Spirit Tarot.
I drew 3 cards for him, but I only remembered the 4 of Cups. That card was position in the middle (monkey in the middle) and I based that on his situation.
The card showed a drowning man floating, but here is the interesting twist. I did not noticed the man nor the ocean. What I noticed was the cup of coffee. I told him that his situation lays at his home. He told me how do I know and I said cause the coffee stood out. He said he did not saw a cup of coffee and see something else. I keep pointing out the coffee, but all he saw was parts of a broken ship. In the end, I just told him that it may be that I was not wearing my glasses and see things differently.
But what I am trying to say is that the middle card is an important factor for me since this is where the situation laid. Then I went to card 3 and 1 (I like to switch positions just to be creative). I don't read the standard RWS meaning. I go based on art, but that is my method.
Just work with whatever spread feels right for you instead of what we tell you. Make up your own spread or find the one you like best, okay.
Hope my tip gave you an understanding.
P.S. I never read with the CC, too much cards for me. As much as I like art that is just too much for me to digest. I like to keep mine plain and simple (lol).
