Most of what you've described would inevitably lead to the establishment of a single party totalitarian state.

Competency tests before you can appear on a ballot, with a commission that reviews the requirements to prevent the exclusion of minorities.

Don't like the opposing party? Just make it part of the test. Today, one party could exclude the other by including questions that agree or disagree with critical race theory, voter fraud, etc.

No elected judges, with stringent training and yearly bias testing. Like a postdoc in judicial impartiality.

Same issue. Who determines impartiality? The party in power? Single party state.

Any person who is a position of trust and power who then acts contrary to the ethics of their role can never be elected. Or have power over anyone again.

Who determines "ethics"? Single party state.

Children must be free of religion until they are 25.

What is religion? You're definitely banning several books, and possibly banning a lot more. Many books can be turned into a religion or contain religious aspects. The party in power decides what's a religion and what gets banned.

USA focused: each state gets one senator, plus one per 2 million residents.

At that point, why have a separate Senate and House? The point of a two-chambered Congress is to balance state and federal power.
