Well I can see your first mistake, asking a bunch of beekeepers. It is a fact of beekeeping that if you ask ten beekeepers you'll get a dozen answers and they'll all be right.
Setting up a swarm or new colony is fairly simple. Just get them to. o their permanent location and let them be for at least a week or two so they can get settled. Bees are home bodies and like there normal jroutine and tend to dislike being disrupted from normal. Hence bees are almost always ill when moved. The best you can do is get them moved as calmly and quickly as possible make all your adjustments and let them be.
Adjustments would be feeding if needed, closing down the entrance of needed, adding branches if needed.
Feed is needed if they have insufficient stores on board and/or a lack of available forage. The opening should be narrowed only if the colony lacks the numbers and strength to defend themselves. Branches or other obstacles are needed only if they have been moved within their normal forage range ie close enough to return to their former location. (I almost never use branches but instead leave them closed up 24-48 to reset their clock and then pull the blocking but leave it in the entrance leaving just a small gap.)
Other considerations would be nearby threats. Large strong colonies in the area are a robbing threat so if you feed consider how. Internal (division board, top feeder, baggie) are safer than external (boardman). Ants are always a concern as well. If you have a solution for them I'm all ears.
