Thats pretty much it for me, the other things you could do is to find out through magical means. i mean you could use a "zone of truth" and straight up ask if that person is a changeling.
but the best would be to find out through magical means, its magic, theirs always a way with magic lol, unless its a very hard to find changeling with a magical item like "An Amulet of Proof against Detection and Location"
Moonbeam- pretty dangerous doe
detect thoughts (if you do it right) ;)

Witch Sight don't work since it only detects if its using magic and changelings don't use magic to transform:
You can see the true form of any Shapechanger or creature concealed by Illusion or Transmutation magic while the creature is within 30 feet of you and within Line of Sight.
Their are some rouge abilities where they can see shapechangers such as the inquisitor.
