Ah man this is such an interesting subject!
I feel more naturally drawn to third person... but that's largely because most of the books I grew up with were in third person, and perhaps because I like ensemble casts and being able to switch viewpoint more easily, but first person can be so interesting, because it's so immediate and everything is reported in this very biased, subjective way.
Frankenstein is one of my favourite books, and part of why it works is that it's an epistolary story, written as letters recording the stories told by characters. Getting Victor Frankenstein's version of events...and then the Monster's version that reveals how unreliable a narrator Victor was being is...mm! Chef's kiss!
I also think the use of first person in The Hunger Games is super-interesting. I think that while the movies had the advantage of being able to really show the revolution building, which the books couldn't, because Katniss didn't see it and we only see what she sees, that book Katniss is a far more sympathetic and interesting protagonist than film Katniss.
Then there's the Locked Tomb series where the first book is first person, and then the second is the really quite unusual second person and it's like "wait, what's happening here?" before it pays off in a beautiful way.
It's definitely a fun and interesting element of writing to play around with! ...Though I mostly make comics and the closest I get to that is the choice of whether to use internal monologue at all (makes it more like first person) or in the case of my current comic, don't (more like third person).
