Would one of these give me more GPIO pins on the PI?It is not clear from the Waveshare manual whether or not the yellow jumpers on the board allow us to select a different set of 8 GPIO rather than the default set (5,6,13,16,19,20,21,26). I suspect not.
That means both of the relay boards will use exactly the same GPIO pins when connected via the 3-way GPIO expansion board.
So, there will not be 16 independent relay channels.
To overcome this we would need to drop the 3-way GPIO expansion board.

They claim it's pi compatible
