I didn't really wanted to metagame that much on my current Survival character and I am running a BoS one. I invested mainly on Intelligence and Agility, that way I can get the best upgrades for my power armor, mostly those that increase it's capabilities. And Agility to help me outside the PA when I need it to complement my robotics expert perks, these robotic expert perks needs you to sneak undetected near a robot and press the activation key. If your level is high enough you can have any robot as companion, including sentry bots and assaultrons. They pretty much fit your Power Armor.
I didnt invest a single point in luck and I am finding lots of Fusion Cores, my biggest problem was to defeat the first deathclaw in concord, but thanks to my knowledge in hacking I managed to get a lot of power armors easily early in the game. I used them without a fusion core, I gave my fusion cores to Codsworth at that moment and I just went out walking and killing stuff from the distance with the laser musket and some rifles while codsworth does the job for me. It has helped me so far nicely. I currently have 7 power armors and I am level 17 with 30 fusion cores. I learned that fusion cores last longer if you never use AP, and if you walk with your weapon drawn after you have the first nuclear physicist perk they dont seem to deplete at all. So if you want to get the best of your fusion cores early on, don't use V.A.T.S. and don't sprint, don't bash either that way your Fusion Cores will last enough for a couple of quests, and I also never use Fast Travel which has helped me to find even more Fusion Cores.
My SPECIAL was this: S3 P5 E1 C1 I10 A7 L1
It's been working so far, but maybe you might not want to miss some dialogues and some settlement options, so maybe it won't suit you. In my case it's been perfect since I am running some sort of a scientist who's interested in technology, he uses a lab coat to increase his intelligence and gain more exp. I also take advantage of the agility to increase my sniping abilities when outside of the PA, and when I am in PA I take a closer approach. I give the Fatman and the Missile launcher to codsworth.
All of this on survival and without metagaming, I just played normally without using guides or anything.
