You basically have two choices, a warm season grass that stays green in summer, with watering (needs about 2 inches of water a week to do this), and browns over the winter, or a cold season grass that stays green in winter, but needs a lot more water to stay green if it's hot (highs over 89F) and dry for 3+ weeks at a time in summer (watering 2 times a week in extended dry periods). If you get regular rain during the summer months you likely have nothing to worry about with many cold season grasses, but if you get warm dry weather for weeks on end in the summer, it won't hold up and go dormant (brown). When that happens the lawn could lose out to strong deep rooted weeds, unless you are prepared to do regular weed killing sprays.

The key to less watering and fewer weeds is to keep the grass long, 4 inches or more will help the grass shade itself, retain moisture and reduce light reaching weed seeds. No grass will do well in heavy shade, even grasses labeled as shade tolerant will want 4-6 hours of direct sunlight. The guide for this is shade = 4-6 hours of direct sunlight, part shade = 6-8 hours, full sun 8h+.
