Hey Luke! Yes, I would definitely recommend shooting multiple angles. For example, Character A's punches might look great from one angle, but Character B's punches look fake from that same angle. Multiple angles also give you more options, which is always a good thing. Remember to always place safety first. Fight scenes are cool and all, but injuries aren't. Rehearse the fight choreography with the actors before shooting. Not only with that help everyone be on the same page, but it'll allow you to focus on other things (like the cinematography, and safety) while shooting. Making it up as you go should only be reserved for extreme situations where you have very little time. As far as a shootout scene, I would advise thinking about what emotion you want to draw from the audience. If the goal is to put your main character in a scary situation, try to think of angles, sounds, and choreography that will achieve that feeling. If the goal is to have a "cool looking" sh ootout scene, think of what elements will bring that result. So pretty much, before beginning any filming, know what you want. It'll help the shooting process, and the end product will benefit hugely!
