Variable font "Style name" best practice

Hi, I was wondering what is advised to put in the “Style Name” field of a variable instance. I don’t really like “Regular” and I am using “[Font Family] Variable” as the Variable Family Name.

If upright and italic are separated in two different fonts, I usually take Roman and Italic.

Forgot to mention, its all in one

Then I would leave it at Regular, perhaps Roman, because they are elidable names.
