It's... it's basically all products. Virtually any product on iOS would function and perform and integrate better if implemented by Apple. It's just a question of at what point it gets popular enough that they want to bother doing so.

iOS is a special case because of how locked-down it is. Not only can't third-parties do things like draw over other parts of the UI or add items to system UIs, they can't even (truly) run in the background.
Of course, on Android, apps can do all of these things and that's part of why it's a security nightmare. Which is why as I said, there's no clear answer to the problem. But it is a problem.
I looked through every app I have installed on my iPhone and I only found a couple that would fall into that category. I have a shopping list app which Apple could theoretically implement as a feature if it wanted to (but not fully, as this particular shopping list app allows me to share lists with android users), and Authy.
The rest of the apps I have installed are just interfaces for 3rd party services. Apple doesn’t have the power to subvert the value of those services any more than any other service provider does (Apple has a maps app, I still use google maps).
I guess Apple could also make a Sudoku app if it really wanted to, but I’d consider that pretty unlikely.
I think there’s a strong argument for saying something like Spotify vs Apple Music is anti-competitive, but for rather different reasons.
