We can do that. Do you expect to be using more than 1 of these values 
yourself, or is it just for completeness?

Regarding 3 as default, it makes a certain sense, but then you won't be 
able to iterate through all locations with just 'n'. You'd have to press 
'C-o' and then 'n', 'n', 'n'...

I think the "other" variable would be called something with the word 
"xrefs", not "references", and apply to other commands as well, such as 
xref-find-apropos and project-find-regexp.

So the proposed scheme would not quite work. Maybe like this instead?

 - xref-auto-jump-to-first-definition
 - xref-auto-jump-to-first-<xref/item/match/result>. Or just 
xref-auto-jump-to-first.
