Without knowing all of the details, if you are set on Square D,
( I like square D ) go with a NEMA 3R NQ Panelboard. This may be a bit of a stretch for a residential electrician to grasp. You want to insist on QOB ( bolt in breakers, not QO plug ons ) You can spec the interior with copper buss ( CU ). It will cost more than a Home Line load center. I purchase this this type of material on a weekly basis. If you really want to blow his mind, ask him to use "Copper Koat" on all of his connections.
( a real audiophile would insist on an exotic silver paste, but I can not recommend a product that is not UL Listed for that purpose ) The things that you could address are almost endless.
