HOW TO FIND INTERNAL LINK OPPORTUNITIES AND ISSUES

Summary from the TLDR Marketing newsletter

Screaming Frog is effective for finding pages without anchor text, pages that are linking to a specific response code, and pages with a higher crawl depth. Google Search Console is useful for finding pages with high volumes of external and internal links pointing toward them. You can use these URLs as a base to link out to other pages. Ahrefs is more user-friendly when it comes to finding broken internal links, redirect issues, and orphaned pages.
