Like you said, CIN and ARZ are both top 5-6
overall, taking both run/pass into account, at least according to Football Outsiders. It looks like there are 4 teams that are ranked in the top 10 in both categories: ATL, ARZ, CIN, and OAK (no particular order).
Things become a bit murkier once you separate pass protection and run blocking.

1) NE (but 24th in pass protection)
2) ARZ (top 10 in both)

4) CIN (top 5 in both)
5) DAL (but 20th in pass protection)
