When you send a lot of ETH or USDT to a big exchange like Kraken, do they care if its come from a smaller non kyc exchange like Blofin? Do they care if it came from a bridge?
Possibly. A chunk of big or unbelievably big money let say $1m usdt in one transaction and the exchange noticed that your previous transactions arent like that of course they might do some follow up or asked you of some details. Better to send in smaller fractions or like what others said use some dex instead.

It is not about if the coins are too much but even if it is a small amount of money, the exchanges still have tools that track the coin past transactions. Make sure your coins is not linked with something illegal. There is nothing to be worried about if you are doing nothing wrong or illegal.
How can they trace the funds to the source before the smaller exchange or the bridge? A wallet funded from mexc just shows mexc as origin right? Not previous hops?
They have tools for it which their blockchain analysts can use for the tracking. 
Exchanges do have whats called "Know your transaction" (KYT) implemented.
You can think of it as an automatic system that checks the source of the funds. Did it come from a mixer? a gambling site? an address linked to a terrorist organization, or maybe a hack of another exchange? etc. How much of a risk is it? High, medium, low?
A transaction from a bridge or an unknown exchange would only raise suspicion if the original funds you deposited to the bridge, were suspicious for example, or if the crypto platform has been involved in something shady.

I don't think exchanges care about sending your coins from other exchanges. Exchanges only investigate the source of your funds when they suspect fraudulent activity or unusual transactions. In such cases, they may request additional verification beyond the standard KYC process. This is to comply with government regulations that require them to report suspicious accounts to the authorities.
Aside from that, exchanges generally don't worry about where you're sending coins from, whether it's a smaller or larger exchange. Personally, I use different exchanges for various types of trading, including both decentralized (DEX) and centralized (CEX) exchanges.

They care that’s why they are regulated and implement KYC to all their customers. You should use decentralized exchange if you don’t want any check like this.
@omegastarscream said above is correct so don’t risk your money if you knew that your funds came from shady origin/tainted.
I’m not sure what exchange Biofin is but it’s safe to avoid all CEX.
