I would like to say one more thing.
If we are comparing some DoF it must be against the lens with the same focal length. Of course, the "blur" Dof effect depends on many factors, but perspective is not the same. In some way, we can compare only some classes of lenses like 1.4. This is the reason why some specific kinds of portraits are done with fast 28/35/50 mm lenses.
DOF effect let's say the "amount of blurrnes" can be more distinct on a 200mm lens but it is looking like a safari. The distance will be significantly larger for a full-body shot in comparison to a 35/50/85mm lens.
In Nikon camp, there are some timeless gem-like 58mm 1.2 Noct, 28mm 1.4D, 85mm 1.4D, 35 1.4mm G, and others. These kinds of lenses have very specific "film-like" rendering, they are not super sharp across the entire picture and they have many laboratory imperfections, but the pictures are subjectively beautiful.
So I highly recommend you to try it first.
Good luck.
