Sometimes, it is very difficult to picture the gap between sensor measurements simply by looking at technical specs. The visual below might offer you a clearer sense of the sensor sizes in the X-5 and A7 III.

As you have seen, both cameras posses different megapixel count and different sensor measurements. The X-5 due to its tinier sensor is going to make achieving shallower depth of field trickier and the Sony A7 III will give extra detail as a result of its extra 8 Megapixels. Higher resolution can also enable you to crop photographs somewhat more aggressively. The older X-5 is going to be disadvantaged when it comes to sensor innovation.
