Looks like good fun. There's a lot to be said for building a table top style layout from off the shelf items. Progress is a lot faster ;).

no track manufacturer has made the necessary development leap AFAIK...
As some will know, I am using Rocoline with track ballast for my shelf layout. These points have live frogs and in the embedded track, they are already wired to switch polarity when the point changes. The points are non isolating so both roads are always live.
Roco make a DCC controlled solenoid point motor which fits into a space under the ballast. This has three wires. Two are attached to fishplates which I connect to the heel of the point. The third wire has a clip which you attach to one rail to put it into programming mode. Once done you disconnect it, fold it under the base and that's it.
I have motorised four points so far.
I prefer slow action motors to solenoids but for ease of installation this is hard to beat. When using the route setting feature of the Z21, I do sometimes have to ask twice or change the point manually to get what I want.

So long as the fishplates continue to make good connections, the four wires I have from the Z21 will be enough. Two of those wires are for the programming track.

Adding other DCC controlled accessories such as uncouplers or signals will add wires and boxes.
