The typical way to profit from this is to deposit to a centralized exchange, trade it for something else, and withdraw before the exchange recognizes what’s happening. However there are simple calculations you can make with the cost of 51% hashing and then the exchange can bump up the minimum confirmations required for deposits and limit the amount you can deposit for weaker currencies.
In general the 51% problem is no longer easy to profit from except with low quality exchanges.

Not saying it's impossible to do a successful 51% attack, just that it's a lot less trivial than it might seem after checking out a site like https://www.crypto51.app/
Is it possibly to see other indicators like daily volume? (that can also be manipulated ...)

ASIC production for Bitcoin mining exists only with the implicit consent of the governments of the handful of countries that contain fabs capable of leading edge nodes.
It would not be difficult for these governments to secure a monopoly on ASIC production, and at trivial cost launch a permanent attack on the network.
Are you saying they couldn't at a bare minimum force Bitcoin to switch hashing functions?
Why do you think doing this in the open would be more beneficial?
