some of these port capabilities are weird to me.  like on the
ACX7100-48L you can do 4x100 or 8x50, but ONLY one 40g ?!

Probably because 40G is a product 10G lanes. There are only 4 lanes available, and the speed of a single lane can vary. So, 40G is the max speed for the lowest single lane's speed.

Kind regards,
