These are all things that would be interesting, but for the most part video is not the appropriate format. For everything except 1 and 3 a transcript is a much better idea, it's faster, it's easier to skip the fluff and get to the good part, and Google can find it for future reference. For 3 a transcript with screenshots is going to be quite sufficient. 7 actually merits a video.
I spent forty years listening to people like you. I went out, I socialized, met people, all that sort of thing. I never liked it. Everybody told me that I just needed practice and eventually I'd start to enjoy it. That never happened. I finally decided to ignore all that helpful advice and quit. Now I spend most of my time alone and I'm a much happier person.
The funny thing is that in all that time no one ever suggested that if I didn't enjoy social activities I shouldn't do them. For most people this seems to be inconceivable. So if you're a younger version of me and everyone is telling you to go out and practice your social skills just try taking a break. You may discover that you like it.
