Which is better in terms of promotion?

Question

Search Engine Optimization

Hello everyone,
Having posted individual articles on my site in different places of the site (by post type and by page type), I noticed an interesting factor... but I could be wrong. So please explain as much as possible.
And so, there are just pages on the site on which there are some articles formed from the parent.
Пример:
сайт.ру/родитель1/статья1/
сайт.ру/родитель1/статья2/
сайт.ру/родитель1/статья3/
сайт.ру/родитель2/статья1/
сайт.ру/родитель2/статья2/
сайт.ру/родитель2/статья3/
And there are entries on the site divided into headings and tags of the article.
Пример:
If we get to a subheading where a list of articles included in this subheading is displayed, then we see the address:
сайт.ру/category/рубрика/подрубрика/
If we get to an article lying in the heading, then we see the address:
сайт.ру/рубрика/подрубрика/статья/
I noticed that articles placed as page in search engines crawl out better than post.
QUESTION:
Does it make sense to publish articles as post in category with binding to tags, or is it better to write articles as page and make a selection on the main page based on custom fields for posts.
Are there any pros or cons if there are only publications (page) with a selection on the main page by custom fields?
Are there any pros or cons if there are only publications (post) with a selection on the main page by categories or tags?

Answer 1

It's more like a conspiracy theory.
It is only important
1) The content itself, how fully it reveals the topic and can compete with articles in the TOP.
2) Linking and nesting level of the article (the fewer clicks from the main page of the site you need to make to get to a specific article, the better).
3) The theme of the section in which you publish the material (so that the section about dogs does not contain about cats).

Answer 2

Tags and categories are subject to change. This should not affect the URL of the article. The category name has nothing to do there.
