Doors or floors
You are over thinkerizing . Take a Piece of the hardwood . Put it on the floor in the doorway on Both sides , Put the door in with the jams on top of your hardwood loosley sittin on the floor , Measure the STOCK door and jamb, set up distance too the hardwood , It should be about 1 inch . This is because people add carpet or a matt , The door won't hit this , If you cut the door jamb down so the door sits 3/8m above the floor , Then put a nice walk off matt there and see , if the house is unlevel the door will swing unlevel , it will hit the carpet , same thing if you set the jambs on the floor Then cut the jambs to install hardwood , Don't try to out thinkerize , If you don't understand go to a door store that deals with doors and ask them about Jamb and door height difference , A picture tells a thousand words , If you cut your jamb to get the 3/8 and the floor is unlevel , Then the door will swing and scrape the new floor , , Also if the house is old and the walls near the doors compliment other unlevel parts of the structure.You will soon see that you should not cut any door jambs untill you at least make a mock set up with a couple finish nails in the Hinge side .You and a helper can use a flat bar to pry the jamb side and hold the latch side so the door is basically where it will sit , If it looks like you want to or could cut the Jambs and make the door closer to the floor then go ahead , but I rarely hear of this , usually a door and jamb are a stock fit ,on Front entry doors the most often problem with hardwood is the jamb is on the floor , I come in to add hardwood .then the door is too close to the floor for the door to swing over the matt , , On new construction they use a piece of plywood under the jamb and threshhold , Thats a different deal because you want the whole threshold to be up so the door seals at the bottom , Interior door have no threshold seal and people usually just install the door stock as is , If stock as is is way to big a gap for your taste then cut the jams , But none of this is really the RULE , , But it's normal to set the doors up stock as is on hardwood ,Play around with a 4 or 6 foot level and see if the door framing is within 1/2 inch plumb . The most 3/4 . If your floor is more than 1/2 out of level near the door and the jams are 1/2 out then leave the doors stock so they don't rub the floor , Thats the best I can tell ya , Except if all this house is built well and all tolerances are 1/4 inch or less you could have the doors closer to the floor ,
