Is there a reason you prefer the dimmer over the switch? The switch would be to code with or without local control, but either could be used as basically a button device without actually controlling the load: both support disabling local (and/or remote) control, so pressing the buttons (or, if remote, even Z-Wave commands) do not affect the load. You get presses, holds, and releases as Z-Wave Central Scene events on the Red Series for either the dimmer or switch (on Hubitat and SmartThings, these get translated to button events; on any platform that’s open enough, the scene events should be usable in some fashion).
A dimmer at 100% (or 99 in Z-Wave terms) is not the same as a switch that’s on. Many types of loads will not like this. The dimmer itself is also not rated for some load types, e.g., motors/fans, so you’d have to be careful what anyone plugs into the outlet (bulbs should be fine but obviously this isn’t permanent wiring so you never know what may happen). If the reason for the dimmer is that you don’t have a neutral (at the switch), the dimmer is unlikely to work well here — it needs a minimum load without one that your outlet, even with smart bulbs, is likely to vary too much with to work well. If you just want to dim a smart bulb by holding the paddle like a smart dimmer, that — as mentioned above — would work just as well with the switch.
Just some other things to think of besides the above!
