"http through a proxy" uses a different form of requests from "http".
nginx as a client does not make the "http through a proxy" request when
it is talking to a configured upstream server.
The general "forward proxy" server will expect clients that talk to it,
to make "http through a proxy" requests.
Your specific "forward proxy" server might be configured to
"transparently" intercept "http" requests and make a best-guess effort at
interpreting them as if they had been "http through a proxy" requests. And
that might work in many cases.
If that works well enough in your specific case, great!
Only you can know whether it works well enough in your case, to be worth
investigating further for problems.

nginx as a server does not specially interpret any "http through a proxy"
requests that it receives, and it does not try to follow the "http proxy
server" rules for handling requests and responses.
If what it does do, works well enough for you, great!

Maybe those many blogs refer to cases where the combination of their
client, their upstream proxy server, and their configuration of nginx,
works well enough for them.
In which case -- great!
You should be able to build a test nginx configuration based on those
blogs, to see whether it works well enough for you, too.
Good luck with it,
