> Using left click to select as well as move feels really unnatural to somebody coming from other RTS games.

Is there a documented standard for RTS controls, at least for baseline features?

Not that I've ever come across, but Blizzard RTSs would have to be the gold standard. Age of Empires being second. Looking at those franchises would cover the majority of player expectations, at least in terms of basic mechanics like attack-moving, move-commands, unit selection, and so on.
