Oats for instance would help add fiber, broccoli would add tons of vitamins and minerals/antioxidants, etc. There a a few basic principles that all diets must adhere to to get results you desire. All the extra 'fluff' is personal choice. Meeting calorie and macro needs is arguably the biggest factor but consistency is up there as well. Your point on monotony is very important. I can't eat the same things day in day out without getting tired of them which breaks my diet. That is reason enough for me to get other sources for carbs but it may not be an issue for OP.
I feel bad for hijacking the OP's thread like this but got a couple more questions. It's maybe going to sound a bit of a tenuous link but anyway. For me personally, it makes me feel psychologically better to consume complex carbs, whether this is a placebo effect I am unsure. But would this psychological boost perhaps turn into a physiological response in terms of hormones, in particular dopamine and seratonin, which would in turn help to inhibit cortisol, etc. and allow a possibly more productive state in which to train? Again, I base this wholly on how complex carbs affect me personally and my own perceptions.
