Question for Catholics and Orthodox?

This always confused me about christianity (I am not gonna ask protestants cause they don't have any concrete beliefs other then hating catholics). The holiest life path for a Christian is to be a hermit or a solitary monk/nun sitting in a cave alone praying to God. Next down is to be a priest, which could be celibate or married (catholic/ orthodox), but if married, cannot rise above a parish priest. The next down is brother/sister, which is also celibate. The next down is a celibate lay person (virgin), and THE LOWEST possible vocation in holiness is marriage, where you can only have to have babies (which means you only get to have about 3 times in your life to get the average number of children, who in turn should strive to be celibate) I only thought about this recently for the first time, but if I am alive today, it means that all of my predecessors were never involved in any holy/ religious orders, which makes me a hereditary non holy person. Kinda made me a bit sad but also curious about why there are no avenues for holiness for those who want a family?
