I have imported this material: texturehaven.com/tex/?t=brown_mud_leaves_01 , it includes AO, bump, diffuse, displacement, normal, roughness, specular PNG files. This seems to be the standard package that a material download comes with, however I have not found a decent tutorial on how to incorporate all of the following to get the result shown on their download page I can get something half decent just plugging the nodes in but I can’t seem to figure out how world displacement and bump offset go together.
