Acrylic and latex are the same, both water based/born material and a good quality paint like Dunn-Edwards or Sherwin Williams will hold color/fade resistance (chalking-especially on darker colors) better for the duration over properly cleaned and prepped surfaces. The spray nozzle size will depend more on the specific sprayer brand/model being used so I would inquire with the equip. mfg. on that. I highly recommend doing it before the end of April at the latest. That dry heat out there is no fun to paint in.
