I ordered BW1-998-002 OE blades for my 2019 S4. The various web sites state these fit.. Actually the do fit however the drivers side blade is about and inch or two longer. The blades I removed are part number 8W1-955-426 and ***425. Neither of those appear to be what the Audi parts sites have as a 2019 S4 correct replacement. One site shows they were replaced by the ***002 version. Interesting they have changed the length and if you happen to get the ***002 and compare the drivers side before installing they do fit and work fine.

8W1 998 002 is the front wiper refill set for the type 8W left hand drive. This is true for the 8W sedan, wagon, coupe, and sportback. The cabriolet uses a different wiper set, 8W7 998 002. But it's just that, a set of parts, a composite part number. So you're not going to find 8W1 998 002 on either physical refill. The parts catalog is aware of the component part numbers, 8W1 955 425 and 426. But the replacement catalog part is only the set pair.

No clue what the actual blade lengths are; the catalog doesn't say. B8 era 8K and 8T were 609mm driver / 509mm passenger (basically 24"/20", and apparently it's the same for B9). What were the actual lengths of the old and replacement blades? Were they actual Audi OE parts or third-party fills?
