Page is a not externally linkable

But Googlebot definitely can and does index iframe content. In fact, there are some posts here with people trying to keep their iframes content OUT of the index because Googlebot is finding it and they don't want that. If I had a site where I wanted some insurance that Google would index the iframe content, I'd put some straight links at the bottom of the page - pointing right to the docs that normally appear in iframes. Then I'd put a script inside those docs that slapped them back into their parent page if they were displaying as orphans. That would create a simple, direct link trail for Googlebot that should not ever be problematic. You might also include a <noscript> tag with some minimal navigation back into your main pages, just for those surfers with js turned off.
OK - a site search here produces many reports of iframe content being indexed by Google. Also there are other reports of iframes not being indexed. Something like every other kind of content which may or may not end up in a particular Google index.
