If it can be restated as “I will on average be more effective at achieving my goals if I only adopting falsifiable beliefs,” for example, then it is equivalent to an empirical belief (and is, incidentally, falsifiable).
If it can be restated as “I should only adopt falsifiable beliefs, whether doing so gets me anything I want or not” then there exists no empirical belief to which it is equivalent (and is, incidentally, worth discarding).
I think it depends on what the PoF actually is.
