Best practice to preserve the link juice to internal pages from expired domain?

[adorninvitations]

This question relates to setting up an expired domain, that already has quality links, including deep links to internal pages. Since the new site structure will be different, what's the best practice to preserve the link juice to these internal pages?

Export all the internal pages linked to using majestic Seo/ ahrefs etc, and set these pages previously linked to?

Or 301 redirect these pages to home page?

I heard there's a Wordpress plugin that 301 redirects all the 404 errors successfully preserving all the potential link juice.

Or 301 redirect these pages to home page?

This is something of a no-no. Google states that a 301 should be used to redirect one page to another that is similar. If you can't find a good match, you are better leaving it as a 404.

I heard there's a Wordpress plugin that 301 redirects all the 404 errors successfully preserving all the potential link juice.

As above, if you have a plugin do this for you then you could find that old URL's are redirected 'en-masse' to the same place, which will do you no favours.
