So I'm curious what category people feel their Wizards should be in, ranging from:
What do you mean "should be"?
Like, what age should products present them in art? What age should we play them? What?
In products - I hope products present wizards of a variety of adult ages, races, genders, body types, and so on. Diversity in presentation is a good thing, not just in wizards, but across character types.
I'm okay if products stick to depiction of adults. They probably ought to put some thought into how they approach children in deadly situations.
In play - whatever's good for your table is fine.
