Quite often, its hard to visualize the contrast in sensor dimensions purely by researching specifications. The picture below may provide you a more clear sense of the sensor measurements in the SZ-11 and A7R III.

To sum up, each of these cameras offer different megapixels and different sensor dimensions. The SZ-11 with its smaller sensor is going to make shooting shallower depth of field more difficult and the Sony A7R III will provide you with greater detail using its extra 28 Megapixels. Higher resolution will also help you crop shots a little more aggressively. The more aged SZ-11 will be disadvantaged when it comes to sensor innovation.
