It's interesting how things are similar but different across the countries. Here in the US you can get GFCI breakers, but they tend to be more expensive than the outlets. The outlets can also protect all downstream outlets.
We also have AFCI (ARC Fault) breakers mandated for most residential circuits. This is another reason for the GFCI outlets since some locations like laundry areas now require both AFCI & GFCI protection.

My guess is you have a switch loop here. In this case, you would have 2 romex cables coming into the ceiling box. One cable is the input line and is always hot. The other line goes down to the switch. The one going to the switch probably has some sort of black marking on the white wire. This indicates that this white is not a neutral, but is being used a a hot.
At the switch, you'd see both the black and the white with black marking attached to the switch. When the switch is on, it connects both wires.
Before you go to far you should use some sort of connecting testing to confirm if you have a switch loop or something more convoluted.
If you have a switch loop, you would normally wire the ceiling box like:
- Input black connects to switch loop black
- Input white connects to lamp white
- Switch loop white (with black marking) connects to lamp black
- All grounds connected together
Here's a diagram that I found:

I don't recall if there's code regarding whether black or white marked black should carry hot to the switch. My preference is to use the black wire.

If you vent out the soffit, consider using rigid ducting instead of a flexible hose. It's harder for a fan to push air through a flexible duct, so the fan will work better. It also allows you to put a small drop from the bathroom fan to the soffit exhaust vent. Doing so will allow any condensation that forms to drip out the soffit exhaust vent.
