Are there any major issues that will come from leaving unused GPIOs, all of pin 8-19, left floating rather than pulled down?

Hello Kevin,
Leaving them floating may lead to unwanted radiated noise in EMC testing depending on the device configuration and the pins may float to a unknown value based on leakage current. So generally it is recommended to use pulldowns per the datasheet recommendation.
