Module development and code questions

Here I am again!
In Drupal 7, I've always used Rules a lot for some automations. I got to have dozens and dozens of rules in some projects.
Now, studying Drupal 10, I also intend to be able to use them a lot.
But right off the bat, I ran into the kind of problem I don't have the ability to solve.
Simple thing for expert friends, I think.
When I'm inserting a rule, more precisely a condition, where I want to compare two fields of a content type, we have the option to browse the fields in "data selector" mode.

I need to stick specific comment on top of others which will remain from oldest to newest. When it's stick on top it's replies must be with that comment.

So I made links in .module file which will take method from controller

Hello friends.
Unfortunately I'm here again asking for help.
I know I've already spent my two tokens on questions, but I leave here my supplications for new doubts.
This time I searched for everything and not even ChatGPT could help me.
What I want, and I already did this in Drupal 7, is, through crontab, to activate a function inside a Drupal 10 module, fully activating Drupal, to execute the code in a module.
I found 3 solutions on the Internet, but none of the 3 works.
Important consideration:

I am stuck on this problem:

I have a content type authors with fields: field_authorname, field_authorpicture, field_authorbio.
Then I have a paragraph type: author_selection with field_author (referenced type authors)

In contenttype news the field field_news_content is paragraph author_selection selected.

now I want to show field_authorname, field_authorpicture, field_authorbio by use of a twig template.

I just don't get the values of the paragraph. 

Anyone can help? 
Thx

I would like to be able to find the origin of an error like

[Saving a node]
Warning: Array to string conversion in Drupal\Core\Entity\Sql\SqlContentEntityStorageSchema::castValue() (line 2579 of core/lib/Drupal/Core/Entity/Sql/SqlContentEntityStorageSchema.php).

in a minute or two.

I just spent two hours discovering that the error came from a contrib module.

I've got a setup on a Linux workstation with a local MySQL, Apache, Xdebug, VS Code (with a gazillion extensions)... And still I resorted to lowly trial and error.

Hi guys.

Sorry for my crazy and basic questions.

I'm trying to put a form in a very simple custom block.

But I believe the "#markup" is filter my form.

Thank you!! (I know it's is a very bad practice, but please!).

THE CODE:

<?php
namespace Drupal\bloco_simples\Plugin\Block;
use Drupal\Core\Block\BlockBase;
