Advices for LED strip organization in my kitchen

Hello!

I need advices to realize my first project with WLED.

Find below the front view of my kitchen and a layout of it for better understanding.

I would like to put a LED Strip under my kitchen furnitures called 3 and 4 (about 3 meters lenght) where 4 is two shelf. The controller will be located on the furniture called 2 on my picture. I want to put a RGBW strip (I want white color). My first question is: in your opinion, do I have to put 1 or 2 led strip ? Which reference of LED strip, controller and psu do you recommend for safer use ? What is the best path for strip location to make all of this working well ?

Many thanks for your advice!
