What about prefolds and flats folded into a flip, super easy wash routine :-) Or if you want really easy, I use Joey Bunz Babykicks hemp inserts in my flips. So simple to change and wash. Then maybe you can use prefolds with a booster for nights, I stuff in a BG 4.0 (I generally don't like stuffing pocket dipes, but they work beat for us overnight).
