In the end, it is always up to you on how you want to design your Interface. Some people like to play with the standard WoW UI, others like to have their action bars hidden and have weak auras in the middle of their screen. As I said, you as a player need to feel comfortable with your UI.
General recommendations I always give in regards to building a UI are:
- Have your player and target frame somewhere in the middle of your screen; the same goes for resource bars and boss mods.
- The damage meter can go somewhere in the corner or side of the screen and should be made small. Otherwise, that can distract you too much.
The most helpful addons are WeakAuras, Plater, Details and BigWigs/DeadlyBossMods. All of those are highly customizable and will help you a lot.

I would recommend playing with Weakauras as it's a super powerful Addon which allows you to track basically anything in the game.
You can find a weakaura package that fits you at wago.io or you can create your own package. You can also ask your streamer of choice to see if their Weakauras are available to the public.
