I think pgbench is just not that great a model for real-world usage
pgbench's default workload isn't a good model for anything. It wasn't a particularly real-world test when the TPC-B it's based on was created, and that was way back in 1990. And pgbench isn't even a good implementation of that spec (the rows are too narrow, comments about that in pgbench.c).
At this point, the only good thing you can say about pgbench is that it's been a useful tool for comparing successive releases of PostgreSQL in a relatively fair way. Basically, it measures what pgbench measures, and that has only a loose relationship with what people want a database to do.
