You could ask around with some of the Japanese or Chinese vendors. From what I've looked around at and asked about, this is all I can tell you (and it could be wrong):
For China, the aesthetic for Cymbidiums is more...philosophical.
If you watch this video, you'll get some level of understanding.
"An Introduction to East Asian Cymbidiums" - Invidious
Basically, Cymbidiums in China are like a representation of spring. The flower come out of the ground, and "burst" open with new life. The flowers also (generally) stay under the leaves, which represents something but I'm not sure what.
For the Japanese the spring component is the same, the aesthetics are slightly different. The Japanese like smaller, clumped together, round things. They also like variegation more than the Chinese, or at least that
seems to be the case from seeing the Chinese and Japanese varieties of Cymbidiums out there from US and Asian vendors. There are some nice variegated Chinese forms of Cymbidium
sinense that are great looking, but there's overwhelmingly more variegated varieties of the big 3 East Asian Cymbidiums from Japanese growers than Chinese. There's also
far more colored flower varieties of Cym.
goeringii from Japanese and Koreans than the Chinese.
For the Japanese, it doesn't seem to be as a philosophical thing compared to the Chinese. It's more about overall aesthetic.
I don't know about cutting off new growths, but if you look at bonsai and Neofinetia
falcata, the Japanese will "train" their plants to grow a certain way. For bonsai, this is obvious and required to grow bonsai. For Neo. falcata, you'll see some people stick little rods in their moss mounds to keep the plant from making keikis on the sides of mounds or jutting out on the sides too much.
I say this because if you look at a lot of pictures from plants in Japan in the the nice painted clay pots (which here in the US will go for well over 100 USD), you'll see that they generally are in a nice clump of multiple plants on the top of the moss mound. This looks especially nice when they're variegated and/or are a bean-leaf variety. Not everyone does this though, as Neos are very different from growing bonsai. A lot of people just let Neos do whatever they want, and they still look good.
Again, this is all observation. For what you mentioned about Cymbidiums, I have no idea.
