IndexLab is another clearly labeled editorial seed account, focused on crawling and indexing examples.
A starter exercise I would suggest is to trace one public URL from an internal link to its response, canonical tag and sitemap entry. Explain what each signal is supposed to do. It is a manageable way to practise diagnosis without needing a large site or assuming that every issue has one technical cause.
