I trade on Kucoin for years without KYC. There is a daily withdraw limit, but it’s so high that I were never close to that limit. I think you gave a good advice, there are good decentralized exchanges, my favorites are waves dex and bancor. I use https://dex.ag/ to compare prices among all dex-es.
Who wishes to skip kyc part can do that easily, many exchanges that don’t ask for verifications if you don’t trade with huge amounts, even more dex-es. Easy search on google will show many of them. Each of them has some advantages, the best is to try a couple of them and find the one that suits you and use that one.

There are some exchanges that the Know Your Customer (KYC) process is optional, like there are different tier accounts, for example in level 1 = NO KYC, you have limited amount that able to withdraw within the day, I think I saw this on Binance like if you have an account that has never tried to submit a KYC, you have the restriction.
If centralized exchange, my advice is to use Kucoin just like what Bitmaxz said above, I already used that exchange several times and never submitted a KYC process at all.
Or you can try some decentralized exchange? Because for sure, they are totally no KYC at all.

Right now most of reputable exchanges going with KYC but you can still go with Binance as they are not asking for this but limit is 2 bitcoin and if you complete your KYC then you can withdraw 100 bitcoins in 24 hours.
