I2C is ugly compared to UART, stay away from it as much as possible, though it is good for connecting multiple sensors on the same wires in a small network. If you meant PCA9685 (not PCA6985), those boards can be cascaded/extended just by setting address bits on board, but it's still ugly as a protocol.
UART between picos can easily work at 2Mbps (200 KB/s), it's what I am using for debugging.
