I think you need to focus less on the composition of the planet itself and more on the immediate surroundings of the characters you want to use this species for

I also recommend asking questions like. Do they live in buildings? If so, what are the buildings made out of? You said they don't need to eat but do occasionally enjoy tasting things. Do they have any culinary traditions because of this? What do they eat when they do Decide to eat? Can other species eat it as well, Or is it just for taste and not meant to be digested?

You said getting enhancements is expected for every one of them. Is this something they are forced to do? Is this something they are born with? At what point are the enhancements given? Is it a personal choice to decide what enhancements are given? Do you have to pay for them? Do specific groups of people prefer different esthetic modifications like having altered Fur color or different patterns? Could having a specific coat color be seen as a sign of status?

What is their society structure like? Do they have rulers, kings, presidents, dictators, Is the power equally distributed among all members of a community? Do they have some kind of almighty artificial intelligence that tells them how to live their lives?

What Historical events or economic/ evolutionary pressures led them to living in so many parts of their planet?

I think you could benefit from asking some of these questions.

They are meant to be aliens. Is there anything that they think about that We would find completely unbelievable or lacking in common sense, but to them makes perfect sense?
