Yes, this will work. However, you cannot select all the vertices.
Fairing requires some unselected vertices.

Here are some useful function for selection:
expend_vertex_selection():

reduce_vertex_selection(): 
https://doc.cgal.org/latest/BGL/group__PkgBGLSelectionFct.html#ga569127b818c04bfca7a5a5bca5b0bc24
locate a point within a mesh:
