Active vertex color set is selected one in Color Set Editor (under Mesh Display
menu), painting is activated by Paint Vertex Color tool (under same menu). Once
the tool is active, you get Tool Settings window by double click on tool icon
in Toolbox (small vertical toolbar on left side). By the way, vertex color are
nicely exported via FBX, even a lot of them, I'm using Maya vertex color
painter for exporting 'weight maps' to Houdini.
About weight maps for deformers, perhaps easiest way is to activate Paint
Attributes Tool (under Modify menu), once mesh is selected (no need to select
just a shape). In appropriate tool settings window, it will show what is
paintable. If not , like with painting the lattice deformer weights, prior to
Maya 2018, afaik common Maya workflow is to create deformer on mesh copy, and
to introduce it as Blend Shape target.
On positive side, for what it worth, it's possible to use Maya procedural
textures (ramp, noise and such) for modulating some deformers like Deform by
Texture, or, for adding a noise to animated channel, so on. In Maya or Max,
textures are evaluated before render time, so it's possible to display
procedural textures in viewport, too.

Subject: Re: OTish - Maya equivalent to weightmap in Softimage?
Right, thanks Enrique. I found that, but how do I actually get to paint values
into this set?
My apologies, but the documentation is not very helpful on this issue.
