I recommend tech tree because it unlocks key abilities like jet packs, lock picking, system targeting in ships, increased cargo capacity, better ships, etc. and then science for the engineering upgrade skills to improve weapons and armour. On the hardest difficulty for space combat, the key is to upgrade the ship class to mount more weapons, improve targeting, get more efficient ship parts. Tips aren’t needed for fps combat because it isn’t that difficult, you just have to watch out for some high level alien fauna that can melee you to death in a couple hits. Body is useful only for the perks that increase carry weight, allow you to run longer and if need be, stealth and phys damage reduction which are all low tier perks. In a game about carrying stuff and running forever, the perks are better the sooner you get them.
Combat is completely useless. I wasted 2 or so points before realizing it doesn’t matter, you can pick any combat playstyle except for stealth and unarmed and dominate (which are body perks) without perks in the tree. Social is also mostly useless but you’ll want persuasion for dialogue options, 1 point in theft to gain pickpocket skill (not a priority) and you’ll get manipulation for free during a quest (again not a priority).
If you hit them up early, then you’ll easily have all of the key perks early in your playthrough and can waste the higher leveled points on the superficial ones.
That's great. Thanks for the suggestions.
