Zero for both.
I think I am rather unfairly influenced by my bad first impression of YouTube polyglots, where two of them came to an old language forum I was in, and I couldn't stand them. One would post cringy videos of himself talking to immigrants very obviously without their permission, and the other had a stratospherically misguided concept of his skills (he'd even "correct" learners' Spanish badly, sometimes writing worse versions than the learners' original attempts...).
I've occasionally watched videos by other polyglots, but generally I haven't found them interesting.
Regarding SLA research, I simply don't read about it. There was one time when I read an undergraduate textbook on SLA (not at school but for fun; I don't recall the title but it was like a collection of essays in a normal non-academic style except for the use of references), and while it was interesting it didn't have much about methods. I remember one essay was basically a philosophical discussion of ideas of what "success" means in adult language acquisition, exemplified with study cases of individuals with inadequate pronunciation and/or grammar who had nevertheless achieved decent success in their lives in L2 environments. Very interesting in social/sociological terms, but still, not about methods.
I seem to be doing well enough as a learner as it is, considering the (not so great) effort I put in most of the time... Introductory textbooks, grammar books, and native input along with a good dictionary (and also, ideally, a translation, which then makes the input an informal bilingual text): all that and I'm good.
