I googledSeveral creatures do have the ability to Constrict as well as Engulf, too. Carnivorous Blobs and Giant Amoebas (who have their own sort of "Engulf" action that involves pulling something in rather than running it over) have both traits.
constrict engulf site:2e.aonprd.com/Monsters.aspx
and received five hits: Carnivorous Blob, Giant Amoeba, Shoggoth, Wemmuth.So it exists but not exactly common.
PS. Sadly constrict and engulf are actions, not traits. So I see no way of filtering for them directly.
