Non-racial druid forms

Bit of a weird question, but something I've been thinking about the last couple days but haven't really made a decision. Also not sure if this is beat suited for this lore sub or the rp sub. My thoughts are more from a lore standpoint though.

Just been wondering with all the recent additions to druid forms over the last couple expansions, of the "non-standard" druid forms do you think there are any that suit (or really don't suit) certain races more than others?

I've mostly been sticking with the standard racial forms, but I often use the more plain raven flight forms on worgen (think they're called duskwing or nightwing or something), and recently been using the dreamtalon(?) travel form as well since I thought it looked kinda wolfy lol.

Always use a stag and owls on night elves, and usually the cheetah for tauren due to suiting the plains and savannahs of mulgore and the barrens.

I don't know if there is any lore/background attached to any of the new optional forms, except for maybe the druid of the flame cat form?
