You can change Noto Sans CJK SC to Noto Sans CJK SC Bold or Noto Sans CJK SC Light, and it turns out that the thickness of the dash \symbol{"2E3A} has barely changed
Bold:
Light:
As long as [RawFeature=+fwid] is turned on, it will be like this, whether you use —— or \symbol{"2E3A}, you can compare it with when [RawFeature=+fwid] is not turned on, the thickness of the Chinese dash is obviously different from that of em dash in Western which follows the thickness growth.
This will cause the dashes to appear very thin when in regular/medium/bold/black, which doesn't match the text very well
