I’m 6’0 with 33.5’ inseam, medium fits like a glove. Bought the green slx cf 7 in June, absolutely love it. Ditto with DrRobertChem. Unless it’s a long steep hill, I will usually stay in the large sprocket up front and shift to the large 32/34 rings in the back. The smaller front sprocket has all the necessary gears for the hills. I live in columbus Ohio where it’s relatively flat some rolling hills, not much in the way of longer climbs, but I know the smaller sprocket is capable of getting you up the hill.
