I know things about show, no tell rule in narrating the story
If the fight scene is not really meaningful, and or would be monotonous, I would just tell it with a timeskip. For the most part telling is lazy writing, but there are exceptional cases where it speeds up necessary information that would be awkward or boring or tedious to show.
However, when talking about plot critical fight scenes between major characters actual effort is needed. A fight between major characters isn't merely "kick, punch, kick, punch" or "sword slash, sword block, sword slash, sword block". I believe that fight scenes where the characters' actions represent their inner natures surfacing are great.
For example, a villain character shouldn't just swing a sword, they should beat down on their opponent viciously and show their contempt and hatred with every attack. They should ridicule their opponent verbally as they fight, maybe reveal that they one who killed the protagonist's mother was them all along. Their attacks should be just as cruel as them and representational of what's inside their black heart. Maybe they use the environment, like kicking sand into the hero's eyes or using a trap.
I find creative fight scenes much more interesting than ones with too many restrictions/rules.
Here's a video on fight scenes I thought was great.
Edit: Ohhh, I thought this was an Ellen Brock video. I was wrong. Anyways the guy outlines typical problems with badly written action/fight scenes, and offers suggestions for improvement. I'll summarize all the critical parts here in note form.
-PROBLEM 1- the fight feels separate from the story
-you paused your story to describe a fight, bad
-reveal who your characters are through their actions
-good, your fight is meaningful and exposes new parts of your character or fleshes them out more
"What I think a fight can do for a story is it can either reveal or confirm or change something profound about one or more of the characters who are involved."
-Marie Brennan
-PROBLEM 2- I can't follow the action
-do not go into massive detail here
-bring the setting to life
-maybe give at least one paragraph to describe the fight area
-the environment is part of your fight
-my example, "She felt her foot slide on the loose gravel as she stepped back to dodge."
-you can make a map of the location for yourself so you can choreograph the fight
-PROBLEM 3- The action is boring
-is your fight just kick punch kick punch?
-make it a problem solving scene
-eg. "I want to defeat you to save someone. I want to get past you. I want to prove something to myself."
-get into your players heads
-what is at stake
-in the fight they make their moves, which bring them closer or farther away from victory, and after the moves they have mental reactions to the consequences of their moves, get in their heads
-PROBLEM 4- Too many details
-Let the reader choreograph for you
-write so that your reader is the one imagining the scene
"Show them early on in the fight how each weapon moves through space --- make that vivid and visceral. [...] The reader will then be able to fill in the action while you describe what your characters are saying, what they're thinking, and what's showing on their faces. In other words, help the reader to choreograph the fight so that you can spend your time on the drama."
-Sebastien de Castell
-capture and convey the idea/feeling of the fight
-PROBLEM 5- Visual fights are more interesting
-don't try to play to the strengths of films, because prose has it's own unique strengths
-1- use all your senses, touch, taste, and smell are things that films can't do
-PROBLEM 6- Things feel unrealistic
-it doesn't need to be real, but it needs to feel real
-Add elements of realism
-1- Real fights are fast and brutal
-2- Real weapons are heavy, you will likely want to use your whole body
-3- Training takes time
-4- Recovery time from training and fights
-5- Sometimes people die from an infection, or a spear to the back, they aren't immortal
-PROBLEM 7- There is no reason for this fight
-Build tension before the fight
-good fights don't happen just because it would be cool if they did
-you have to outline what your characters wants
-merely by informing the readers that you have two characters who want different things, and are willing to be aggressive then you have built the foundation for a future fight
-Example, Informing the readers that there is a bomb underneath the table and even the characters don't know, the reader will be on the edge of their seat with tension
-PROBLEM 8- It's too long
-Keep it focused
