I realised I don’t have favourite female you tubers specifically but Emily Wilson is good if you want Catholic pep talks, Karima Mckimmie for makeup that isn’t caked on. All Things Adrienne if you enjoy girly, lifestyle videos (diet, fashion, beauty, relationships). I don’t know the last two that well so I’m not sure how Catholic/family friendly they are. But I can’t remember them cursing or anything so should be fine.
I enjoy the scientific side of things like skincare at times so I usually watch Lab Muffin Beauty Science.
