It wouldn't matter to make it Cute or Pop, but mainly determined by balancing the total amount of characters and brands of all types. At this point, there are two cute idols and two pop ones in Four Stars, so it's fine for Venus to come up with any type of idol they want.

The concern could be from the old series which still lacked Cute idols/brands until its end.
