Advice on Schema Structure for Rankings

Hi! Need your kind advice please. I been trying for years to get to no 1 google ranking for the keyword 'logline examples'.

My Article

• 3000 word article
• lots of backlinks
• social signals

Competitor

This is what baffles me. There are 3 results ahead of me, short articles without any strong content, but they rank first.

In my research it is an agency that does the schema for all 3 top results (universities .edu) and they definitely know what they doing.

What I think possibly the secret is that the following schema structure is their waterfall in one module:

article
- is part of webpage
- is part of website
-- publisher
-- potential action {search_term_string}
-- breadcrumb
-- potential action (read action)
author
mainentityofpage (webpage)
-- part of website
-- publisher (organization)
-- potential action {search_term_string}
-- breadcrumb
-- potential action (read action)
publisher
-- same as

Then a secondary element called 'hcard'.

Please, what do you think the magic element is here, how are they able to rank as no 1 with so little content?

Could it be the images, potential action, or just the way it is structured?
What's up with the (#) after the links?

Most appreciate your thoughts 🌿
