Best Minimal UI Setup

Hi All, new to Wow and I'm looking how I can make the most of my UI... I'm looking for something clean where there's not an information overload like you see on most UI's... I'm just a casual player really and still learning the game, and don't want to be too overwhelmed at this point... I quite like the default UI but I feel like It could just be a little better in terms of action bar layouts etc...

Any advice would be great. Nice and clean, no numbers all over the screen, just QoL things
