Hey Matt,
Don't eliminate power nozzle canisters from your search. Most Mieles and Kenmores have a slot on the main body from which you hang the power nozzle front edge down to minimize your storage footprint. These take up no more space than an upright.
If you had only wall to wall carpeting, I would not look at canisters (you have to clean forward into the room, which leaves you walking on your just cleaned carpets - with uprights you can clean easily while "backing out" of the room starting at the far corner).
But since you have bare floors with area rugs, a canister is a more flexible and easy to use solution. The large head on an upright will not easily get under and around your furniture and you'll end up using the onboard hose a lot anyhow.
If money is no option and you prefer uprights, go and get the white Miele Cat and Dog upright. Consumer Reports gave it high marks in all test categories (carpets, bare floors, suction thru the hose for tool use, noise reduction, emissions control) BTW, it looks like all the Miele uprights come with a generous 40 foot power cord.
If you want to really make your life easier, add the wonderful cordless Swiffer Vac to your arsenal! This $40 stick vac will clean and dust all your bare floors with ease in between vacuuming...and it hangs on a hook on the wall. My 85year old Mom swears by it!
