My uneducated guess is that the resonant frequency doesn't matter that much and is more relevant when using the piezo as a buzzer, not a sensor.
By cheap Chinese, I mean the piezos they sell on Aliexpress and ebay and don't state the brand nor any technical details about them beyond their diameter.
If you have the positional sensing board, you don't have to worry about the first half wave polarity - that's what it's for. And if you don't have it, positional sensing will be a struggle anyway. And a voltage divider shouldn't be required either.
