I've always been placing FBP under dataflow. Regarding distinguishing features though, AFAIK, one of the more important ones is that in FBP, connections between processes are done via named ports on processes, and that the wiring of these connections is thus enabled to be done separately from the process implementation itself. Dataflow, AFAIK, does not specify how the data network is specified. We tried to describe this feature under the "Reusable component" with a figure (fig 3) in this (open access) paper: https://academic.oup.com/gigascience/article/8/5/giz044/5480570#134301289 https://academic.oup.com/gigascience/article/8/5/giz044/5480...
