Scott, Polikey, by Chris Glasby & Kristian Fauchald, suggests only Arenicolidae juveniles might also have only bearded neurochaetal hooks (ie long handled forms).

Maldanid neurochaeta are not regarded as uncini, which is a term more used for chaetae typically squat and plate-like in form. If uncini have a handle, the head is usually still squat and substantially beak-like. However so-called 'acicular uncini' in sabellids would be similar to maldanid neurochaetae - minus the beard as far as I know, except damaged forms may possibly appear to have a beard. (Sabellid experts may wish to correct me on the nuances or possibly the gross errors of the above).
