Applying this stylesheet at the application level ...

Applying this stylesheet at the application level sorts out text scaling (on a 14" display with a 1080p resolution) but is far from ideal:

import tornadofx.Dimension
import tornadofx.Dimension.LinearUnits
import tornadofx.Stylesheet

class AppStyle : Stylesheet() {
    init {
        s(".root") {
            fontSize = Dimension(1.3, LinearUnits.em)
            fontFamily = "Noto Sans"
        }
    }
}

Used this window to guesstimate text scaling.

You can just use fontSize = 1.3.em

More of a preference to include where em comes from to add a bit of clarity.
