    Holding down mouse-middle only puts a words and lines in a region.
    It does lines only when the mouse is at the end of the line.

    * It would nice if holding down mouse middle in text mode would establish a
      region containing the current sentence the mouse is over.
You can point at the period to get this.

    * It would be even nice if it knew about paragraphs and marked them when
      the mouse is at the beginning or end of the paragraph.

It's supposed to.  But it got broken by the conversion to mode flavors.
Fixed in the source.
