Rebuilding the cache for specific pages

In my WP site I am importing automatically posts from some feeds. After I finish such an import, some posts might be deleted, and others added. I do not want to clear the entire cache, as rebuilding it for a few thousands posts would take time and resources, but I want to target specific pages and rebuild their cached version, as follows:

1. all the new custom posts
2. all the deleted custom posts
3. the archive of the specific CPT that contains the imported posts (first page, and then each page after that)
4. the archives of the related taxonomies (first page, and then each page after that)

For #1, I think I found the solution in an answer, could you confirm this would be the right approach in my case too? https://www.ads-software.com/support/topic/flush-cache-on-specific-pages/#post-17483836

For #2, do I need to do anything extra after deleting the posts with wp_delete_post()?

For #3 and #4, what would be the best method to use?
