Not sure to migrate to CI4

A simple example: some pages are restricted to some users, depending on the user rights. I need to load the page data before checking  if the current user is allowed to visit the page. Filters are not great because I have to load and process the page data twice (once in the filter and once in the controller). Redirecting from models / libraries / helpers is no longer possible. So it must be done in controllers. The problem is that my controllers becomes more and more complicated. Even worse, I can't split my code into functions, because redirection in CI4 is based on return, so I can't redirect from a private method in my controller or BaseController. Do you get it?

And what about throwing an exception? If you encounter any problem in your model, throw an exception, the controller catch it and redirect with the error message.
