Hi and welcome.
For me it seems that it is all a time / money / effort trade off. What you can or are prepared to spend will usually off set some labour.
Looks like you get a barrel with your kit? Does it come with any gas or fitting on the barrel to inject gas?
Have a look around at some other pressure barrels and gas that is required to dispense the beer. You may want to consider buying separate kit and bottling your first few brews....then move on to a barrel.
Have you got a budget?
Bottles are easy. You can pick up suitable types free, or save them as you consume bought beer. But they have to be cleaned and sanitised.....around 40 per brew :lol: and you will need to buy some crown caps and a capping tool.
Bottles are easy to put in the fridge.
A keg is less intensive labour wise....one vessel to clean and sanitise. Cost outlay for the barrel, get as good as you can afford IMO if you go down that route.
You will need additional gas to dispense the beer....most people I know started with the Hambleton Bard gas cylinders and a barrel that accepts the S30 fitting. There are other systems available and all have an initial out lay and on going cost that you need to consider.
Keeping the barrel cool requires suitable space or fridge.
Hope that helps....good luck
