Any RTS games with a hard cap on APM?

I generally play turn based games because I find playing fast stressful, in particular, that there is no upper limit on micro and that you could always push yourself a bit harder and do better. Are there any RTS games where APM is a resource that you have to manage, bonus points if this incentivises you to be smart about giving orders to individual units versus orders to large groups since they cost the same or similar? I'd like a game where the ability to micro is a resource that you have to think about.
