Why was 4K random write chosen as the main workload, and would the conclusion change with sequential I/O?

That's a popular DBMS pattern. We chosen writes over reads, because on many NVMe devices writes are faster and it is easier to measure software latency.

I guess that in case of sequential I/O result would be similar. However with larger blocks and less IOPS the difference might be smaller.
