Depends onf the fight scene. Sometimes its kinda comedic, focusing on timing and a kinda slapsticky description of action. That tends to have a lot of one-liners (whether dialogue or just sentences on their own), and doesnt last too long so it wont wear out its welcome.
Sometimes its more focused on showcasing the characters abilities nad how the fights go. Those get more description of the actual actions and imagery, trying to paint a good image in the readers mind. Those often benefit from internal monologue and body language to show emotion and break up actions themselves. The movements need to be described concisely but clearly, if you're going for this type of thing. I am to understand that these types of scenes are somewhat less popular, most people prefer action that focuses more on the characters emotions, but honestly these are my favorite kind personally.
And lastly the most popular type, where its showcasing the characters emotions using the battle as a crucible. These benefit from very verbose and descriptive language that gives a strong sense of 'vibe', imo. Also, internal monologuing, banter between combatants to showcase their emotional states (Are they angry? Calm? Just focused and murderous? Or maybe cocky and enjoying themselves?). One nice thing here is to use characters actions to show their emotions. A character who is filled with rage will be more aggressive and constantly on the offensive, someone whose calm and collected might be more defensive, someone who is cocky might move with exaggerated swagger. Etc.
