Highly customizable UI Addon Recommendation

[Kerrig]

Hi.
I'm looking for a UI addon that would allows me to make a clean and easy for the eyes UI and that has a high level of customization.

https://github.com/ElvUI-WotLK/ElvUI
augment with https://github.com/Bunny67/WeakAuras-WotLK
add a pinch of pre-designed stuff like https://forum.warmane.com/showthread.php?t=439253
and you got your UI

Searched for some examples of what people could do with those, tho I used weakauras i only used them for stuff like prock indications or buff warnings (for example water shield running out) tho the stuff mentioned in link 3 is a diffrent way cleaner approach and Really like how it looks.
ElvUI also looks lovely gotta try it out (I have only used bartender4 before and VuhDo/Helbot).

Thank you so much for help, much appreciated.
