I would solve that by creating a view like:

CREATE VIEW some_view_name AS 
  SELECT <<fixed columns from tables>> WHERE <<fixed join statements>>;

See also https://www.postgresql.org/docs/14/sql-createview.html

Then you can query that view with your actual select criterion like:

SELECT * FROM some_view_name WHERE <<actual select criterion>>;
