I believe one, being a new boxer, should focus their attentions on the basics. And this would mean a high tight guard.

In time you will develop a style, and it may be having your hands low, high, all sorts of things. But you will find a style naturally that fits your individual set of skills and characteristics.

When you try to predetermine a style for yourself before you have firstly learned the basics, and furthermore/eventually explored the many options out there for yourself, you have created limitations before you have even really begun. Just my opinion ofc.
