You have a choice on the water pressure based on the pump and controls you specify. The higher the water pressure, the more it will cost you in electricity - it takes energy to provide that extra pressure. A conventional well uses something like a 60/40 pressure switch, and the pump fills the tank until the high point, shuts off and the pressure drops until it gets to the low point. There are a few ways to make the pressure remain constant rather than varying each cycle: a variable speed pump (expensive) and a cycle stop valve. If you search on the well forum, you'll find lots of discussions on this.
When you have the plumbing done, consider having them plumb a hot water recycling line and a recirculating system for the hot water. This will keep the water hot while it is running at all locations so you don't dump a few gallons waiting at the end of that long run for it to warm up. While with a well, you may not pay for the water, it certainly costs to pump it out of the ground, and then, you may have a septic system you would be dumping those extra gallons into for no good reason. It's cheaper and more convenient to use a recirculation system. The recirculation system has a very small pump, and you can put it on a timer or an occupancy sensor so it only runs when you need it. Also, insulate ALL of the pipes well.
Go with a Bradford White tank with a powered damper using your propane for fuel. Good quality, good economy. Size it per the local codes based on the number of bathrooms, or whatever they require by code. Go bigger if you plan a multi-head shower or a large soaking tub.
