AFAIK, there is no particularly compelling hypothesis, one way or the other, wrt which form of matter arose 'first'.

While the origin of 'normal matter' (baryosynthesis and nucleosynthesis) can be addressed, from particle physics, the lack of details about the nature of DM precludes any hypotheses re the origin of DM (other than that is almost certainly existed at the time of the surface of last scattering).

This question is meaningless, in terms of 'the Big Bang theory' ... 'dark energy' is merely a placeholder term, used to describe one feature of the universe, in terms of GR models. After another decade or three of investigation, it may turn out to be a particularly poorly chosen term, in that it isn't 'energy' at all.
