Insulated rim joists, should I add cavity insulation too?

I insulated all the rim joists before framing my basement walls. I used foamboard, PL300 and Great Stuff foam to adhere and seal the foamboard to the rim joist area. I did NOT put cavity insulation back in (most of the fiberglass I pulled out was unusable) Im now working on lighting in the finished ceiling, so I have access to a lot of the joist bays, albeit from 2' away. Should I take this (final) opportunity to shove cavity insulation up to the foamboard? Could I use blown in instead (blow it in from the 2' away and fill that 2' with blown in)? Or do I really not have much to gain either way? Note this is a finished basement with a finished drywall ceiling (Im adding another layer of drywall over the existing because I dont feel like trying to patch holes and get rid of texture) Thanks in advance.
