You can be critical of tropes even if they occur in a lot of Japanese media. The infantilization of women is not some unassailable, unimpeachable holy trope that can't be called out because "that's just how Japan is." For one, that's not necessarily "just how Japan is" and generalizing this as inherent to Japanese media is kind of insulting. For another, all art is open to all criticism, both fair and unfair.i don't get why people keep complain about anime being anime ortoo japanese , it is like someone complain about games too american or western , simply i don't get it .
Final Fantasy as a series has had its ups and downs in regards to its treatment of women, but I don't think this problem is all that widespread in the series. In fact I think it's mostly limited to games written/directed by a few specific people. FF14 certainly doesn't treat its female characters this way (although Hyur women do have that silly "anime girl" run animation and Miqo'te are fetishy as fuck).
