project-find-file and project-find-regexp are the main ones. Useful 
when... you want to visit a file within the current project, or search 
it for a regexp?

xref-query-replace-in-results could also be mentioned, given that it 
allows the user to replace the matches with some other string (both in 
project-find-regexp output, and in xref-find-references output).

It's extensible via project-find-functions, which was the core design goal.

In the core, we have only two backends indeed: one using VC, and another 
for EDE.

Though I'm not sure if the latter has any users, and its implementation 
is very simplistic.
