It seems to me that research scientist is a post-postdoc in industry, so all these textboxes for cover letter (or "introduce yourself") are the way for a researcher to say "Here's how my extremely specific research area actually applies to your business objectives"

Depends on where you apply. Universities and national labs probably expect a research statement which can be seen as a cover letter. But that is not something that can be generated by a bot. It will be your personal research statement akin to a grant proposal.
