Blade length decides how much hedge is cut per pass and how heavy the machine feels at arm's length. A 450mm blade is easier to control on detail and topiary work. A 560mm blade covers a run faster and is harder to hold steady above shoulder height. Reading the blade against the hedge rather than buying the longest available is what makes the machine usable overhead.
Power source follows how long the work runs and where. Petrol at 22.5cc goes anywhere and runs while there is fuel, which suits a long boundary. Corded machines at 500W, 550W and 600W are lighter and quieter with a lead behind them. Cordless 18V and 20V machines go anywhere within a battery.
Reach is a separate question from blade length. A pole hedge trimmer puts the blade at the top of a tall hedge from the ground, which is safer than working off a ladder with a running blade in both hands. That is a different machine rather than a longer one. A pole trimmer also keeps the operator away from the cuttings, which fall clear rather than onto the ladder.
Two-in-one machines run a grass head and a hedge head from one powerhead, which suits a garden where neither job justifies a dedicated machine. Hedge trimming attachments at 440mm fit the same principle.
