You probably have this nice IPC3 review noted already or have been sent the link, but it would be a good starting point, with a nice table.
Wilson, W. H., Jr. 1991. Sexual reproductive modes in polychaetes: classification and diversity. Bulletin of Marine Science 48: 500-516
Caveat: brooders tend to be studied & reported on more often because they are easier to find! So might distort statistics. For example Polydora group - the first polychaetes to get me interested as an undergraduate. Fascinating critters. Both BR-CAP-PLK & BR-CAP-DIR /LEC in Wilson's groups.

Subject: [Annelida] meroplanktonic polychaetes
One of my zooplanktologist colleagues, Miodeli Nogueira Junior, wants to
know if there are any published or unpublished estimates of the number
(or percentage) of polychaete species with planktonic development (not
including holoplanktonic ones). Any educated guesses? :-)
