Getting the feeling that the first person narrator is actually writing the book would detract from some stories, I think – make you feel kind of self conscious on behalf of the narrator, as well as make you feel like they're a bit vain, perhaps, to be writing all about their life in such detail.
Ah, but that's the thing - then you get the chance to come up with an interesting reason for why the narrator is writing the story! And maybe that would be because your narrator is vain...though that would get a bit wearing!

But yes, as you said, this only works for some stories. Definitely not something you would want to do all the time. But it's an option I often consider these days when I'm thinking about a new story.

Now that sounds interesting! I had an idea for a story where two women go on a quest, and ultimately the heroine dies because the other woman betrays her. But then the heroine's husband/love interest/not sure who he would be captures the betrayer and forces her to write an account of what happened, because he really wants to know what happened to his beloved. So you could have the betrayer trying to justify herself, and perhaps you could also have a complex character in the husband/love interest/whoever if he's really angry with the betrayer and is trying to force her to tell the truth.
Sarai, I like your two reasons for why you would choose a first-person narrator! It hasn't occurred consciously to me before how such a narrator can increase the twists in a story because of their limited knowledge. It would be easier, for instance, to have a character misunderstand something and mislead the reader, too - a plot device I love when used successfully, but I find pretty annoying when the author doesn't manage to fool me! "Oh come on, you stupid character, can't you see that...?!"
I've also found that a first-person narrator can leave you guessing if they don't reveal much about themselves. With any other character in the story, you have to actually see them
in the story for them to be part of it...and so you learn more about them than you would about a first-person narrator that's basically just a mysterious voice telling a story. You see some of the narrator's personality, but they can hide who they are if they want - their gender, their age, their place in life, their role in the story...you know? This was done quite nicely (though not to an extreme extent) in A Series of Unfortunate Events.
Also, have any of you read
Code Name Verity? I wouldn't recommend it offhand - it has quite a bit of swearing, torture, references to sex, etc. - but the first part was one of the best examples of a self-aware first-person narrator, not to mention an unreliable narrator (always fun!), I've read.
And, by the way, I'm sorry if my use of "they" as a singular gender-neutral pronoun annoys anybody...to me the use of "they" as a singular gender-neutral pronoun is just an instance of perfectly reasonable and normal linguistic change, and so I have no problem using it...
