Comment on PSA: Try FreeCAD Link Branch (it's a big improvement!)

One body per sketch was always a deal breaker for me, so it’s good to hear that limitation is gone.
Do you know if sketches are still required to represent a single continuous face? For example, 3 concentric circles would not be allowed because it is ambiguous which parts are “surface” and which are “holes”. F360 doesn’t impose this limitation because it allows you to select individual sketch faces to move into 3D space, whereas FreeCAD considers that a single operation on the entire sketch.

FreeCAD does indeed perform a single operation on a given sketch, but I think the problem you’re encountering is the fact that FreeCAD cannot perform any operation to solidify a sketch that would result in more than one discontiguous solid.
You can, for example, totally extrude 3 concentric circles into a pad provided they intersect another solid surface that at the very least spans the gap between the edges of the circles. Your example in particular results in a cylinder with a hole in it, and another cylinder centered in that hole. The geometry is not actually ambiguous:

The above is just one sketch to create the rectangle, and then the other sketch is precisely what you described, three concentric circles of random diameter:

Link can do this with a single sketch+pad (which is what I was referring to in the original post)
