Your search skills are probably fine. There is just so darn much yummy info on UESP wiki that it takes lots of time there to learn how to really navigate it well.
Yes, I used to cap at 30, but then I figured out there is not a single piece of leveled quest reward type of gear that I really care about, so now I cap at 20. Nothing I want or need above that. Capping low, does increase the challenge of attribute gains however because you have fewer levels to achieve them. I find that some efficient leveling techniques help. I also just plain ignore several attributes which not only makes building the other attributes easier, but much more sharply focuses and defines my character. My current character is a mystic archer and completely ignores endurance, strength and luck. The only reason she pays any attention to personality is purely for RP. Lol..
