Generally, it is hard to imagine the gap in sensor measurements only by researching a spec sheet. The graphic here will give you a clearer sense of the sensor measurements in the FE-5020 and A7R IV.

As you can see, each of these cameras come with different megapixels and different sensor measurements. The FE-5020 due to its smaller sensor is going to make achieving shallower DOF trickier and the Sony A7R IV will render greater detail utilizing its extra 49 Megapixels. Greater resolution will make it easier to crop images a good deal more aggressively. The older FE-5020 will be disadvantaged in sensor tech.
