Generating your own passwords is usually a bad idea, as humans are bad at being random, and create things which are easy to remember. The best solution to this problem is simply to use a password manager, something like KeePass for example. It will securely generate a different long and random password for every site you need it to. All these passwords are encrypted and stored locally, and can be protected with a combination of a master password, a key file, and 2FA.

As an aside, in your examples above I would disagree with your second example (orange text) being "okay". This practice is only trivially better than using identical passwords across sites. I would probably rename the first two categories to "very bad" and "bad", and remove "okay" altogether.
