I think all official park and ride parking lots have 24h time limit but usually there are residential streets with unlimited street parking nearby. Something like Huopalahti (local train) or Kulosaari (metro) might be good candidates as they don't have big commercial areas near the station. Google Street View can provide some hints where others park. Of course break ins and vandalism happen but those should not be the worst areas. Optimal place is of course where there are plenty of other cars parked but not so many that they look like they are for some special occasion.
Otherwise that ferry terminal parking seems like good deal for some security.
