Take a look at Troy micro flip up sights. Might suit your needs, currently more available than the CZ OEM sights.
I used standard Magpul flip up sights with a Holosun red dot on my scorpion, along with an SB1913 brace (looking to replace with stock now that it’s SBR’d). Cheek weld has never been an issue. Consider that if you get a folding brace that attaches to a 1913 tailpiece adapter, you can mount the brace higher on the 1913 to help with cheek weld height.
