Do nice water pump pressure switches exist?
If you look around online, you'll find a huge array of products for pump control but I think you're right, there's really just the Flowtrol / Square D or very similar products available at low cost for home use.  

(By the way, good for you insisting on a UL listed product from a trustworthy, reputable source.)

If I understand your question, your problem is you occasionally have to use the tiny little override switch to get the pump to start after pressure drops below the low threshold, probably after a power outage.  

You could wire a manual override switch to bypass the pressure switch, but I'd hesitate to do this.  This would ideally be a double pole, single throw switch, horsepower rated for the pump's voltage and load, in a standard switch form factor so you could mount it in a regular electrical box.  That's definitely not an easy to find hardware store / big box item, but the major manufacturers make this kind of switch in their industrial product lines.  I'd want a momentary switch so that you can't accidentally leave it on, which could overpressurize the system, run the pump dry and burn it up, etc.  

The reason I'd hesitate is because I don't know if this would override some other protection that is built into that simple looking Flowtrol switch.  For example, it might limit the override action so that it stops the pump when you reach the upper pressure limit, preventing the pump from over-pressurizing the system.  

If you shop the industrial pump / control products, I am sure you can get what you want, or at worst build it, but for a suitable product UL listed and approved for potable water, the cost would probably be prohibitive.  That's how pumps are controlled in industry, but it's EXPENSIVE.
