CLK0 and CLK1 are grouped together. ?CLK2 is isolated off by itself.
So likely best to use CLK2 for the most critical signal source, whatever that is.
Ideally CLK0 and CLK1 would be locked together to reduce birdies. ?Perhaps CLK1 is a 12mhz BFO and CLK0 is set to 5*12=60mhz for the first mixer of a double conversion rig. ?
Better yet, blow an extra $1USD for a second Si5351, and shield them from each other. ?But then you need some way of talking to them both via I2C, and they likely have the same address of 0x60. ? ?Perhaps use an analog switch or logic gates to turn on the I2C clock into one Si5351 at a time.

So, it seems that swapping the two should be ok. Meaning (may I please get this right!) use CLK0 for VFO and CLK2 for BFO.
For some reason I seemed to remember reading that CLK2 was used for the VFO for some reason. Anybody remember anything along those lines?
