Hello Alexis and her bf,
I've been writing for more than 2 decades now, and when faced with a question like yours, I like to go around what it entails. Many stories I've written for myself and never kept were first person, dynamic fight description with such a bare bone narrative like an adult video store's repairmen comes over porn.
If it's something I write for others or I just want to entertain others, the stories are usually longer, but there's of course a cheat code you can use, namely you can form your fights into a series where your character needs to be established only once. You don't need to listen to me, but if I write it, I'd spend the introduction first on how your fights are unavoidable, either because of your hot temperament, low tolerance to alcohol, or nurture among brothers/slash sisterhood where you became the alpha. If the latter is the case, they definitely should be always first person since a queen be would never tolerate being narrated in 3rd unless she's the queen of Sheba and the royal scribes are expendable.
The next is the scenery. My cheat would be to establish the place you frequent the most (if there's one or the most well-known) and compare other places to it thereby shortening further introductions. How you would describe opponents, for me again depends on why you fight. It would surprise me if you would write you got really drunk but 2 pages later you can perfectly recall the kanji for friendship on her arm. The more believably antagonistic you are the less you wish to go into detail on them or compare it to yourself how much better you are.
In conclusion if these stories talk to you deeply, it should be first person, but suppose there'd be a fight where you got drunk and couldn't recall all detail, narration could switch to your boyfriend explaining it to you in the third person. These are my two cents.
