Addressing your verbosity complaint:
Spend time learning to read the lowest level documentation possible.
It's dense and terse, which makes it difficult to read. But the knowledge per word is the value.
For example, you were mentioning relying on tools to build your environment and manage your installation. Don't. Learn how venv and pip work. Learn at the lowest level. Build up. Stop learning from the top and building down. Save that for when a project demands it.
Understand "why", not "how", and then you can evaluate whether a guide is wasting your time.
