common or shield shield of sensor's wires?

Other Hardware General Electronics
1

I have three sensors mounted (BMP280 -I2C, TEMT600, DHT22)- to a total of 11 wires. Planned length from sensors to the board is around 2 m.

I have 2 types if wires in my hand:
a) 2 wires - common shield
b) 2 wires - individual shield.

I also thinking to:
c) 11 individual or paired wires, shielded by a Diy aluminium foil shield (I admit - is going to be very ugly)

Question is:

  1. shall I shield each wire strand individually?
    or
  2. shall I use a common shield to all 11?

or, well, not shield them at all?

I am also concerned influence of the wires to the read values (I have 16-16 awg wires) and mutual interferences.

Thank you very much for helping me to advance!

Twisted, not shielded, cat-5 or cat-6 seems the right choice.
How about this.

I2C
pair 1: SCL+ground
pair 2: SDA+ VCC

TEMP600
pair 3: OUT and ground
VCC from I2C wire

DHT22
pair 4: OUT and ground
VCC from I2C wire

Grounds only joined at Arduino end.

As far as I know, those computer cables are difficult to solder.

You are right - I counted cables as they are now mounted on breadboards. But once getting to the field device, it does not make sense to keep separate cables for each GND pin of each sensor.
