Logging errors are helpful, primarily when an error occurs in the future, background apex jobs, or flows. Especially when you want to investigate why some background jobs are not working as expected and you want to know how frequently the jobs are failing.
Using the following solutions you can find the apex error exceptions easily. You can see why the error occurred and on which line of code the error occurred. You can see the errors in a list view and can do reporting on a specific error.
