Yes, I think you could change https://github.com/pydata/xarray/blob/b76a13f042571d01ca07461f13125a030f7297ea/xarray/core/formatting.py#L144 to np.issubdtype(x, np.floating) so it formats all floats.

The other seems a bit more complicated: set_title has a template https://github.com/pydata/xarray/blob/b76a13f042571d01ca07461f13125a030f7297ea/xarray/plot/facetgrid.py#L461 but it uses format_item to format the numbers first https://github.com/pydata/xarray/blob/b76a13f042571d01ca07461f13125a030f7297ea/xarray/plot/facetgrid.py#L26 you could probably add a float_format="{:.4}" keyword argument to this function and set_titles.

We'd be happy to take a PR.
