The trope you're looking for is
Tropes Are Tools...
I don't have everything on TV Tropes bookmarked, but I'm fairly well acquainted with it. And anyway, Ruby's entry already includes
Spotlight-Stealing Squad, which in turn references those other related entries.
But anyway, whether or not Ruby is a cliché, the point is, as you imply, that she not only had a personality, she actually had a
story built in; she didn't just have random stuff happen to her, she actually had a start point and places where she or the readers wanted her to go. Which puts her well ahead of most of the characters in the setting, to be frank, fun though most of them are.
And Ruby's basic character arc is actually, from what I've observed, quite common to nerds, myself included, though not universal. (And she got there a couple of years later than many nerds.) There's all the petty grief at school, the social difficulties, the sense that other people (including siblings) have worked out how to do stuff that remains incomprehensible to the young nerd... But then you get away from the social environment that consists largely of your past mistakes and people who remember your youthful stupidity, and discover that there are people out there who'll decide that they like you for yourself, and that the nerd impulse to analyse and read about everything can actually be quite useful if you learn to play it right, and that you can quietly dump a few of the sillier nerd pretensions and social fallacies, and hey, odds are you can get a decent job which allows a bit of living well as the best revenge... I always wanted Dillon to give someone the gay "it gets better" speech, only for Ruby to realise that it applied to her even more.
So yes, she's relatable.
