It depends what effort you're willing to expend for what result. There are plenty of lower-maintenance gardens you could have, and those usually center around working with the soil and climate you have, to grow native plants and others that will thrive in the same environment, and making sure you're working with your sun exposure, not against it. There are groundcovers that are useful to combat weeds, instead of that unsightly mulch. We put down grass clippings from our lawnmower, because I can't stand regular mulch. I have a bed of prize roses and a sizeable vegetable garden that need occasional weed control, but other than, congenial plants and grass clippings and weeds it is! I like my natural mixed lawn better than I do a single varietal, weed-free one.
