Context sensitive cross reference using Cleveref and Varioref

I am blocked to make a command (called pref{<cross-reference>}) for cross-references using cleveref and varioref. I would like it to be able to adapt to the context :

• First, I would like to be able to remove the comma when the reference is on the same page as the referenced object. This is what I currently have :
  

• Secondly, I would have liked to know if it was possible to add the name of the chapter or section to which reference is made without calling on crefformat and thus be able to use the command cref with its default behavior in other contexts.

Here’s what I currently have:

Here’s what I’d like to be able to post:

documentclass{article}
usepackage{varioref, hyperref, cleveref}
setlength{parindent}{0pt}
defreftextcurrent{}
defreftextfaraway#1{p.~pageref{#1}}
crefformat{figure}{#2textsc{Fig.}~#1#3}
crefformat{section}{#2textsc{Sec.}~#1#3}

newcommand{pref}[1]{(cref{#1}, vpageref{#1})}
