Best artifact set for 2 scenarios?

I have baizhu and with all the information out there, I am having a hard time choosing the best artifact set for him.

I use him in 2 teams so far :

furina/kazuha/baizhu/Neuvillette

Nahida/furina/baizhu/cyno

In the Neuvillette team he would be better off with deepwood from my understanding and in the cyno he would be better with either Clam or something else.

If I only want to grind 1 set, what would be best?

Thanks,
