i colonise a similar number to you on average, i generally just colonise all the green and yellow planets in the first wave. 1 thing i do is resettle pops from some of the colonies to others of them to get a couple of the colonies up to 10 pops quicker just to reduce the drain on my capital a bit quicker. this way i get the advantage of having all those colonies providing pop growth but dont have to sit with half a dozen colonies draining my capitals pops for 30 years.
i do build gene clinics but i dont build them as soon as you do. if i have 6 colonies i would probably build something like 2 cg, 2 alloy and a research and a unity as the first buildings on them depending on exactly how the start goes. it doesnt really matter what goes where, you can always rearrange things later to get specialisation bonuses. if you want robots then pick a couple of planets you really want to develop quickly and build robot factorys there and build cg and other stuff on all the others first and wait for the second slot for robots on those. will slow down your early growth a little but will stabilise your economy quicker as well.
i always build an alloy foundry first on my capital.
