Ideal is one of those subjective words. I would say 50-60 psi is a good range. If pressure is too high, it is hard on faucets and valves. Most code requires a pressure reducer if pressure is over 80 psi and a booster is pressure is below 15psi. I am on a well and use a 40-60 pressure switch.

I also live somewhere where everyone is on private well. I always let my customers know, however, that a 40/60 puts a bigger workload on the pump than a 30/50. They usually go with the 40/60.

We're 80 to 100 pounds although working in houses with wells they seem to do fine. Don't really miss the difference if you haven't had it. We get a lot of complaints about lack of pressure when people get a low flow faucet.
Some kill their dandelions by blowing them out of the ground with a garden hose.
