A terrace made of concrete is an option for me. My favorite is natural stone, but it must be slip-resistant. But wood is also a good option, just more demanding to maintain. But in that case, it's nature for nature.
Wood is indeed good and fits well with nature. But it also needs more maintenance. That prevents me from using wood on the terrace. So I have laid ceramic floor tiles on our terrace. I think that also looks good.
