This is a unit I have.
The unit that you have listed states for spaces up to 2300 sq. ft. I plan on building somewhere between 2500 - 2600 sq. ft. Would this require 2 whole home dehumidifers (one larger, and one smaller)?

If your house is properly sealed during construction, you should not need any dehumidifiers. Whichever HVAC contractor you use should do a manual j and a manual d to calculate needed load which should keep the house at a comfortable humidity level.
I sealed up all the top plates from all the penetrations except for the exterior walls. I also made sure the windows were sealed and flashed. I believe you can overdo it on sealing a house. I think having the exterior walls not sealed, because I couldn't get to them, was a good compromise in letting the house breathe.
I put in American standard silver series single stage air conditioners. Nothing special. They pull all the moisture out of the home without running a ton. I did insulate the hell out of the attic with cellulose. I imagine in some spots I have close to a foot and a half to 2 ft of insulation.
I will say though that if you have a gas range with oven it will add moisture to your home so make sure you have good ventilation over your range.
I hope this helps.
