I'd think that 4 terminal resistors are overrated.
They sure do have some advantage if you want an accurate absolute resistance value, but chances are your gadget has to be calibrated anyway, and that makes stability more important then absolute value.
The 4-wire Kelvin connections are mandatory though and you have to take temperature effects into consideration. For such SMT resistors it's common to put the high current path on the outside of the resistors, and take the voltage sensing feedback from the center of the insides of the pads. This is also shown in the "recommended land pattern" on page 2 of the datasheet. I do like the solid copper pads inside the connections of the resistor you've chosen. For temperature effects, imagine what happens if the resistor heats up because of high currents. Copper has a relatively high temperature coefficient, and will therefore change in resistance and therefore in voltage drop. When you connect the feedback lines to the insides of the pads, the amount of copper between the "resistance element" and the "feedback sense lines" is minimized. It's probably less the 0.1mm long, and over the full width of the resistor. This is a quite minimal resistance. There is not much that can be improved here with a 4 terminal resistor.
I do have some doubts about this resistor though.
The datasheet of your resistor specifies a "load life" of only 1000 hours at rated load, and nothing about long term stability. 25*25*0.004 = 2.5W and this is also quite a lot of power for such a small SMT resistor.
Also i have another question for voltage measurement, so if i want precise voltage measurements i need a precise adc voltage reference, precise resistors and low temperature coeficient ones?
No, not really.
As Davey Jones has said many times in his video's, stability is much more important then absolute accuracy. Static errors can quite easily be calibrated out, while drift can not, because it changes over time.
Temperature coefficient is important, because a low temperature coefficient reduces changes with temperature. But it really does not matter if your voltage reverence is 5.0000V or 5.2314V, as long as it stays put at the value it was initially.
With calibration you can get the total a few orders of magnitude more accurate than the initial tolerances of the parts.
