Both triggers are being used with different purposes,
describing below:

Before-parameter-form: is fired before parameter is going to
report data model part, code can chan change or validate the
parameter values which are passing to reports' data model part.

Format-Trigger: is fired if returns true then it will
print(display in report) if returns false then can't
print(display in report), actually it's name belongs the
'Trigger' but actually it is not a trigger it is a in-built
function in report.
