Hair style to match face shape

So I'm looking to cut my hair potentially, but I'm not sure what to get. I'm curious as to what type of cut people think I could pull off. I'm open to cuts that take more time to style, and bonus if it's something I can style in different ways depending how I feel, but versatility isn't a necessity. Also, what face shape do I have? Currently my hair is long, I don't have any products to put in it and I wouldn't know what to get anyway. I let it air dry after a shower, I condition more times than I shampoo. My hair tends to be frizzy and dry, yet it gets oily within 2 days.

Here's some examples of previous haircuts i've had so you can get a sense. Currently I have long hair.
