All that I mentioned do very well there no-spray. Temperate fruits can do okay if you get low-chill varieties (chill hours vary from ~150 - 500 hrs depending on where you are in the Houston metro). Apple and pear are most limited, more options for stonefruit, peaches and japanese plums in particular. I grew up in Houston and developed a love for gardening and fruit growing in high school. Urban Harvest is a great organization of great people that offer fruit growing classes and have tremendous experience as to what types and varieties grow well there. They have an annual fruit tree sale in January with lots of otherwise hard to find local favorites (Ponkan and Pong Koa mandarins, Bloomsweet grapefruit, Suruga persimmons, Tropic Snow peaches, Pakistan mulberries, all figs and pomegranates are among my personal favorites). I have a small orchard I planted at my parents’ current home in Dickinson ~15 years ago. We’ll be back for Christmas and I look forward to the fresh citrus!
