Seeking lightweight & stylish thin cladding Options

I’m looking the materials and design for cladding the walls. My preference is to use a wooden tongue and groove slat, but I’m mindful of the weight and thickness. I’m hoping to find some lightweight options that are also as thin as possible. Would anyone be able to suggest some good choices? i saw some example on many sites but couldn’t find any plan.
Thank you in advance.

PVC tongue and groove cladding or composite cladding, which can mimic the look of wood but are thinner and lighter.
