I also was OCD and hated scrappy as I like being in control. Then I tried one of Bonnie Hunter's patterns, her Pineapple Blossom pattern, made it with whatever I had on hand and fell in love with scrappy from then on. I also made it in a controlled scrappy version too and loved it even more. I've made a number of her patterns since then and most often they are scrappy. In fact seems most of my quilts seem to go more scrappy than not. Bonnie's patterns have changed my whole way of thinking.
Right now I'm on a no fabric buying mode and have been since Nov. 2018 so I have to use what I have on hand. Luckily I have a good stash of fabrics including scraps of all sizes so there's no problem for me.
