There are Views, the elements of the dictionary are displayed, the exposed filter is made in the form of a select, it is filtered by another dictionary:
1 - The name field from the term is displayed in the text of the filter element, how can I make it display another field, for example, description?
2 - How to make sure that the list of filter elements includes terms whose selection does not give an empty result?

Answer 1

Exposed filters is the usual form. That is, you can use hook_form_alter in your module to get and change the value of any form element.
Here is an example of a taxonomy field in an exposed form structure:
At a glance - in your case it should work like this:
Iterate through all the #option elements in the desired form field. For each of them:

1. We check for the presence of elements marked with the term - for example, through taxonomy_select_nodes($tid). $tid is the key in the array.
2. If there are more than zero such nodes, we get the term object via taxonomy_term_load($tid)
3. We replace option with the value we need (for example, description)
