I will challenge you on bookmarks.
First, think about what a bookmark is. It's not an article. It's not a mention of your website in the context of a larger article. It is simply a text link with a description.
Who in the real world, in real life, creates links to a bookmark? Not only is it completely unnatural, but it is not a 'valuable' property that will grow in authority. Zero authority whatsoever.
However, it does send a signal to Google that people are bookmarking a website. So that does have some social significance. In other words, it can help your money site if linked directly to the money site.
The other two examples you cite are examples of properties that can accumulate authority through linkbuilding, and then in turn help your moneysite gain in rankings. Those are ideal for Tier 1 because they will help your moneysite.
