I'm not aware of a "standard", though a lot of nodes with omni coverage use
vertical polarisation, because they use a collinear.

It's always an issue, just not in the way you mentioned. :-)  As long as
both ends of a link are running the same polarisation, that link will be
fine.  In high density areas, having some links vertical and some horizontal
can reduce mutual interference and increase available bandwidth.
