Thanks for the reply. In general, I would find something that broke out the analog and digital I/O pins on the headers to screw terminal blocks to be very useful and probably the most flexible. The main thing is to get something with a better mechanical connection for analog inputs than simply inserting the end of a wire into a female header. A reasonably hefty screw terminal block would probably do. Locking connectors like Grove or Molex are also good, but for analog inputs, often it’s one signal per sensor, so you wouldn’t want to have multiple inputs bundled on a single connector. The particular sensors that I’m using (moisture sensors) have 3 wires per sensor: power, ground, and signal.
