Such words in any Preamble are usually meant as a lofty declaration of some ideal, not a concrete political goal.
After all, "ever closer" does not even mean federation, it means a unitary state, which is "closer" than a federation or a confederation.
If you believe that a single sentence in a 1957 treaty can be used as a ramrod to push European federalization from above, you will be surprised by the backlash. European nations aren't mostly interested in becoming provinces of a future superstate, potential referenda in this direction will almost certainly fail, and given the growth of the far right all over the continent, I don't expect the governments to agree to any further voluntary transfer of powers to Brussels.
Also, the European Commission is not a government and is not meant to act as a government that can decide "everything".
The countries that formed the EU have only agreed to transfer some powers to Brussels. Not give it an unlimited hand over everything. And Chat Control is a major infringement of constitutional rights in many countries, where inviolability of communication except for concrete warrants has been written into law for decades.
Imagine a situation if the German Constitutional Court says "this is illegal by the German Grundgesetz, and German law enforcement may not execute such laws". Do you believe that German authorities will defer to Brussels instead of its own Constitutional Court? Nope. Same with Poland etc. Local constitutional institutions have more legitimacy among the people than the bunch of bureaucrats in Brussels.
