What type of Sink Mixer?

I'm having my Laundry renovated next month. I have already purchased everything except for my Basin/Sink Mixer.

I am only having a small sink in up the end of the bench. This is the one that I have purchased. https://www.sinkwarehouse.com.au/produc ... ount-sink/
I don't know if I should put a mixer in that comes out of the benchtop or one that comes out of the wall.
The sink will be mounted on top of the counter - not undermount and is only 200mm wide so not sure what will work best.

Ideally a pull out spout would be good because I can fill a bucket if needed, but this isn't essential.

It is always more practical to have mixer coming out of the benchtop.

I think the same. It will be easier for maintenances and installation too.
