If we compare his case to CZs, both violated anti-money laundering laws, but the key difference is that CZ didnt steal customer funds, while SBF did. Because of that, this case likely wont end the same way CZs did.
Another important difference is that CZ had enough money to buy his freedom, while SBF clearly did not. In the end, those from the US might regret not asking for twice as much, because I have no doubt that he would pay $10 billion.

I don't doubt that he has some hidden wallet with a few million dollars waiting for him if he's released
Maybe, but I somehow doubt he was intelligent enough to do that, because everything he did turned out to be very bad and thoughtless, which ultimately cost him his freedom. However, let's imagine a situation where he gets out of prison one day and decides to access his hidden crypto treasure, and gets caught red-handed again.
It is possible that there are addresses to which cryptocurrencies were transferred that are known to the authorities, but they currently do not have access to them - this does not mean that they will not continue to monitor them in the hope that someone will access them someday.
