To answer your questions:
1. I have no idea about LSOpenURLsWithRole. I am not a Mac developer.
2. I have manually tested the change:

        Button showHtml = new Button("HTML");
        showHtml.setOnAction(e -> {this.getHostServices().showDocument(new File("data/test.html").toURI().toString());});
        
        Button showTxt = new Button("TXT");
        showTxt.setOnAction(e -> {this.getHostServices().showDocument(new File("data/test.txt").toURI().toString());});
        
        Button showCsv = new Button("CSV");
        showCsv.setOnAction(e -> {this.getHostServices().showDocument(new File("data/test.csv").toURI().toString());});

The code fragment above reliably opens the HTML document in Firefox (my default browser), the text document in BBEdit (my default text editor) and the CSV document in LibreOffice (my default Excel :-)

This also works if you just use the plain strings without conversion to an URI.

Here are the printed Java/FX version strings for completness:

    java.runtime.version: 18-ea+16-926
    javafx.runtime.version: 18-internal+0-2021-09-28-174132
