Hive body choice is this:
Deeps, what the psudo standard is. 90 pounds full of honey.
Mediums what a lot of us are going to. 60 pounds full of honey.
8 frame mediums what I'm now moving to from the regular mediums. 48 pounds full of honey.
How much do you want to lift?
You get to choose on foundation. Plastic is almost universially (except for Pierco) is 5.4mm cell size. Standard wax is 5.4mm cell size. Small cell foundation is 4.9mm cell size. Natural worker brood cells run all the way down to 4.4mm with most around 4.85mm or so. You can use large cell foundation (standard) or small cell foudation (not standard but more natural sized). The small cell helps tremendously with the Varroa mites.
I would get a Screened Bottom Board instead of the standard solid ones. Get one with a tray so you can close it up in the winter and open it in the fall. Then you can use the tray to monitor Varroa mites.
I'd get an Italian Hive tool from Brushy Mt. They are far better than the "standard" ones.
Buy a big smoker. They are easier to light, esier to keep lit and worth the extra cost.
Buy a Jacket with a zip on veil. That way you can get plenty of protection until you feel comfortable with the bees. Then you can consider buying just a veil.
You'll learn a lot with an observation hive. It's true you'll make a lot of mistakes, but you can usually figure them out because you get to watch.
I've never moved a split away from the original site nor moved a hive somewhere else to move it back somewhere a few yard or hundred yards away. I've always just moved them when I need to and put a branch in front to trigger reorientation. I shake more young bees in a split to make up for the ones that will leave. I make even splits by facing both to the old location. It's a nice convenience to have another yard 2 miles away, but not necessary. I'd love to have one just so I can have more hives without driving so far. My outyard is 60 miles away.
