Generally very good but mixing button/non-button style is a dark pattern that should be avoided.

If you have 3 alternative actions and one looks like a button, why don’t the other two? It is actually very easy to miss at least one option that way, or otherwise make a mistake.

a "dark pattern" is a UI tactic that is very purposefully crafted to deceive or manipulate a user. confusing button styles as you describe them are just "bad practice," they aren't dark patterns until designers use them with the specific intent of confusing the user
