As some people have said earlier, I think the cute and beautiful definition is up to personal tastes. But I agree that you can make cute and beautiful without having to use CC. And using only content officially in the game can guarantee how it blends in the Sims world as well.
For your sims, I can see you bring a variety of beauty and not stick to the same direction, which is great! Your Sims have unique characters and can express how they will be in the story. I like the smirk vsile vibe of the 2nd girl who has sharp and confident eyes.
I also use CC-free content to make over hundreds of townies in my save file. Or I can say that 99% of my female Sims are CC-Free. I have to use CC for men because the choice of outfits is very few, especially "unbuttoned shirt" (before there were many additions since last year).
I never use CC makeup because I don't know how to use it properly. But some makeup in this game is like CC itself because it's too extreme to use. Beware when it's randomly used in your townies because some are very jumpscared.
