could the power main, which is wet, cause the issue with the downstream breakers
Not normally. A GFCI is only 'aware' of leakage on the circuit it protects, not the source of power. Provided there is power at the panel, the GFCI should work.
Do modern gfi breakers which have no test button,
Hold it right there... Is there such a thing? If there's no test button, are you sure they are GFCI's? Can you post pics or model number?
To be honest, if on a GFCI you push the lever first to off, then to on, and it does not energise the circuit, even with everything unplugged that can be, pretty much your only option is to call an electrician. Testing the cause of that, or replacing the device if it turns out to be faulty, is beyond the scope of DIY.
