Dude, I had problems like that, so I keep exploring to find the perfect system, but it was impossible, I had one with 4 habitable planets on it! I was about to colonize them, one already with pollution, so it was going to be the heavy industry one.
So, I didn't really need the 10 volates production, but without the fuel prodution, they were ok, not great, but ok, I could have gone with them, all with 125-150 hab.
Also found one with a arid with 125 hab, no trans, a cold one with +3/+2/+2 rare, com, vol, and a no atmosfere one, so fuel they were also ok to colonize, with a crioship on the system and a hypershunt close by.
Still ok, but I said to myself, keep looking, found one with all planets with poor resources, -1/0 or -1/-1, an water one with trans, and 0 food, a arid one with -1 food, and I said for my self, men, this system is garbage, the only good think is the gate, it is resource poor, the gas giant is 300%, no way it is going to turn a profit!
After exploring all the planets, guest what, the last system was the best one, you really don't need a +3/+3 resource, just enough to feed your refining, the one with -1/-1 was not habitable, so with the drill and administration it was producing more them enough.
The cold one I placed the lamp, just to discorery that until it reachs size 6, it can't sustain itself! This costed me a lot of money, but when I was finally figured out I could place a gamma core on pop to decrease the cost to 9, took me lots of money.
With a single no-at planet I have 36% of the fuel market, more them that and everyone would start attacking me, this happens with everything! Just because I had 5 planets in this system, I could have 2 of all industries, just one with fuel, This gives me a 450.000 GMP, down to 300.000 after paying salaries.
So, you don't need great planets, I was really said I couldn't use the soil nanites on the water planet, and just had a single no at one, also the hypershunt is 12 of distance, so, no extra industry, but doing the math, 10 volates is hard to get, but 10 trans is almost impossible! You need story point and a gamma core on it! And my colonies are far away from the center, so my colonies lost a lot of shipments, that I normally have stockpile to cover it, even with everything produced locally, the game makes you have shortages from deliveries from other systems, it is a strange game mechanic, you should lost profit from not delivering, not don't receiving goods locally produced.
My point is, don't try to find the perfect system, I see people here with 2 50% habitable planets with the same system, but for what? You need colonies to give you profit and the profit will be high only before you can self sustain, so cost goes down 50% I really don't think I can spend more them 450.000 upkeep in a month, even with an armada that can take down the sector. I was unluck, there is not a single 100% or less habitable planet (unclaimed) on my sector, but I really don't need it.
