As an energy race from another dimension and seeing that they can travel between dimensions, my opinion only, would be that they would have some type of wormhole bonus, ie; starting with that tech of opening & closing or maybe not affected by mines when going thru a wormhole, etc, I do agree with superior Intel, but cunning would be lower then most AI do to them being naive, physical strength low, Diplomacy could go either way depending on how naive you want to make them, since they are pure energy, maybe affected by certain criteria, ie; ion storms, etc,
in a system or anything that could affect/enhance a pure energy race, tho I don't know how you would do this or if its possible to mod in a game.

Maybe a built in defense against non-energy type weapons or something similiar.

sounds good

just some ideas mac
