I'm not sure that Col 3:16 helps definitively, as it could be eiher
instrumental ("Manner" or "Means") or locative; 5:19a is pretty clearly
true dative and reciprocal-- "to each other." I think Eph 5:19b and Col
3:16 are probably both instrumental; (a) if Eph 19b were locative, it
really OUGHT to have an EN; and (b) there doesn't really seem to be any
place here for THi KARDIAi to mean, as it sometimes does, "silently." So I
would think the instrumental--"manner"--or even "means" ("with your
hearts") would be the preferable interpretation here.
