The clips you have pictured are the ones I'm referring to. I prefer the cage (on the left) . I tried large and they felt good on my toes but it's kind of trial and error anything feet related. They're a tiny bit lose but you can tighten the straps to taste.
I probably have 9 or 10 sets of clips but those MKS cages are what I prefer. The ones on the right tended to pinch my toes no matter what position on the pedal I had them and I tried both medium and large.
As far as the converse I'm not sure how they're sized
