In many cases, it's difficult to visualise the contrast in sensor sizing only by seeing technical specs. The visual here will help give you a much better sense of the sensor sizing in the FH8 and A7R III.

As you have seen, the 2 cameras have got different megapixel count and different sensor sizing. The FH8 with its smaller sensor will make getting shallow depth of field harder and the Sony A7R III will provide greater detail because of its extra 26MP. Higher resolution will make it easier to crop photographs much more aggressively. The older FH8 will be disadvantaged in sensor tech.
