Our minds are not very good when it comes to creating random strings of characters. So we implicitly create not so strong passwords and Wallets for ourselves.

I would use either the private key generator of my hardware wallet or dice. So entropy should not be the issue. Variants III to VI use the brain for memorizing the seed words.

It looks really complicated and brain wallet isn't safe because there's a risk where your might suffer brain injury when you're accidentally crash during driving or getting older. Here's the statistic where brain injury has higher chance could happen. You can teach your kids or someone you loved to access your wallet, but if the steps are really complicated, they might also forgot it due to multiple reasons of human error.

I am aware I can forget the seed words. Therefore in each variant II to VI the seed words are written down and hidden.

If you forget your seed words and the location of the written down seed words you can still ask your friend to give you back the USB stick with the manual. Unlock the USB stick and learn that you own Bitcoin and the location of the 24 words.

If you die, your wife will probably worry about money. She will probably check the banking folder. For your funeral she will also check the government documents folder. So she knows that the USB is encrypted with Veracrypt and she knows the password. Since your dad, your brother and your best friend learn you died, they will give the encrypted USB sticks to your wife. So now she has the password and the USB sticks. After decryption she will find one document. She will read the document and learn (i) you own Bitcoin (ii) Bitcoin is valuable (iii) you can sell Bitcoin (iv) you need 24 words + passphrase to use your bitcoin and (v) the location of the words in our house.

I think a reasonably intelligent person is able to install veracrypt and enter a password to unlock the USB. I also think having 24 words plus passphrase makes it reasonably easy to control the Bitcoin wallet.
