I don't seek to look long and lean per se because at 5'1" I am never going to look tall by any stretch of the imagination. And lean is a stretch as well.I am fine with JFE in some looks and don't necessarily aim for an hourglass look. For instance, I like shift style dresses and probably wouldn't feel comfortable in a fit and flare style.
My problem area is my middle; I have a thick waist and a pouchy lower belly. I choose to downplay that when possible and like when a style helps create more of a defined waist. I wouldn't find it fun to wear something tight that emphasizes my belly or creates a muffin top. My butt is rather flat and I wouldn't feel good in jeans that made it look more so. As often as I've tried to wear wide leg pants, I just don't feel attractive with extra fabric in the legs.
As to being ok with looking wider, I think it's relative. If you are a size 0 or 2, "wider" means maybe looking like a 4. That is still no where near "fat" or "big" which I think most of us would prefer to avoid.
