Ferrite bead placement
It depends on the values in the analog section. If both are small (say, 0.1uF and 1000pF, the bead should be upstream. If one of them is bulk or bulk-ish (say, 4.7uF or 10uF) the bead should be downstream of it.
That’s a bit of an oversimplification of course.

If your digital supply is very noisy, has a lot of ripple, or the analog is very sensitive, you might even consider a separate regulator for the analog part.
