I don't know about the Swedes, but the Finns have long valued their independence, and seem to have a well-established ability to maintain something of a balanced and non-confrontational relationship with Russia (& former USSR, at least since the Continuation War). I don't know if they would see NATO membership as beneficial, or as a potential albatross around their neck...

Latest polls show that a majority of Finnish people want to join NATO.
They see NATO as beneficial.
That’s thanks to Putin’s invasion of Ukraine
