Mom cut & color ideas needed

I need some help picking a cut and color that’s not going to make me look super chubby and washed out. I’m wanting something low maintenance and easy to style but I also want to feel pretty again (hence the color). My hair is naturally confused lol the back on the bottom is curly back top is wavy and the front is straight. It also likes to stay oily looking 😣. I also have a round face and I’m a bit on the heavier side so nothing too short and can’t do any super “fun” hair colors because of church. Any ideas ladies? This momma is just trying to keep up with a toddler, newborn, house, and hair and it’s just getting to be overwhelming.
