Like some families, I think everyone has favorites. My younger sister makes ambrosia that our Mom used to make, plus a pink molded salad that's traditional in her husband's family, and a strawberry pretzel salad, and on and on. She makes both turkey and ham at holidays which satisfies everyone's appetites.
I like to make a molded lemon cheese ring sometime during the holiday season. It is on the sweet side, but everyone loves it once they try it. Originally, I learned to make it as a topper to homemade cranberry sauce, but a couple of times the layers split..... Anyway, the lemon cheese goes very well with either turkey or ham.
It's easy to go overboard on sweet sides this time of year. I really like most vegetables plainly cooked, maybe one that has some sweet to it, either plain broccoli with lemon/butter or if sweet, a broccoli carbonera (sp?) salad, with the cheese and raisins, plain carrots or a carrot raisin salad if sweet.
But I think what I really love is Waldorf Salad -- nice combo of fruit/veggies and a hint of sweetness.
Now I need to go buy a few apples.....!
