You know , i tried alot of them. Thats a good sign. I mean, with different position and leader they are usefull. This is good idea to adjust civics to improvements.
The thing is that tech tree is big, and in DW you need something half-vanilla-half ffh teching, that means specialisation and beelining necessary techs for religions/leaders civs.
The best way to see what is still necessary to add i think will be to write small table (ugh its not small, really

) of leaders/civs versus civics. Then check their paths - paths which each civ will choose as optimal, and build some synergies on those paths as viable options for certain leader/civ , that have some synergy.
Those paths dictated by - Traits, UBs, UUs and Offworld Trade resource units.
Then i think it will be more less clear where are holes, what needs to be added, and what we have in abundance.
Sure - there should be no civic that will be universal. Each of them should be viable option in certain circumstances.
I dont know if i am clear enough, hope you understand.
Current civic balance - i find its quite balanced. Just need to check those aviable paths and see if there any option to add some synergy with solar farms/turbines. Example : Some civ should be good with that (Ix?). Ok, Ix... They love Offworld trade, and beeline Liquid Fuel (early military) then Technocrathy>Cybernetics. Hey! there is Refining techniques on that way. That means Turbines. (machines, robots, thinking turbnes)
They have no prefrence to SE/CE, thus thy can get some Economic civic, that will boost windtraps by 1 commerce (hammer?) , and turbines for 1 commerce. , Which unlocked at Liquid Fuel or Refining Techniques.
They are agressive, and they are organized, so Imperialistic civic will not provide great bonus.
Then there can be some Goverment civic ties with Cybernetics as well. I think Technocratic society of thinking machines will love some other type of goverment , than we have atm in Goverment civics list. Lets say Health is less issue for civs that abuse thinking machine factories , perhaps that goverment should provide extra health (Sterile society) and may be something related to unit building (training virtual programms, unit building speed?), so that will be special goverment civic for ones who beeline cybernetic path, and will provide some warmonger synergy and health at goverment slot.
Those just examples, please do not judge strictly, its just direction where we can find new civics/ uses and synergies.
