One thing I would add to that list is learning the local documentation trail
before reaching for a web search.

A practical habit is:

man command command --help info command        # where the project still
maintains info pages /usr/share/doc/PACKAGE/ journalctl -u NAME  # for systemd-
managed services

That usually tells you the exact version and packaging assumptions for the
machine in front of you.  Web examples are useful, but they often mix
distributions, init systems, shell dialects, and decade-old advice in the same
search result.

The other useful "pro" skill is getting comfortable reading scripts with set -x
in mind: environment, quoting, exit status, and where stdin/stdout are going.  A
lot of Linux troubleshooting reduces to those basics.
