I think "that" here is just a matter of choice. But I don't think that "do" is a matter of choice. In my opinion when you say "I do hope" it is like when you say "I really hope".

Sorry, I just saw that you are a native English speaker so probably you dont need my advice.

Yes, the "do" provides emphasis.
