I think it is best to not have a standard selected tool
the point tool is most to the left so, it sounds most natural to have that as standard selected tool, but as the tool is the least useful tool, I don't really like it to have standard selected
the most useful tool is probably the circle tool, but it also feels random to have that standard selected, I think it would be to just don't have a standard selected tool, so that the users understand it first not to tap a tool in the toolbar, before something happens
