If you are talking pipe most is light 40 NB some medium.

So 40NB with say a 2.4mm wall which comes in just under 2".

Pipe is for fluid so it is measured in NB or nominal bore and the NB plus the wll thickness is the OD.

Most car guys talk in OD as when you fabricate stuff for cars you often use Tube which is talked about in OD rather than ID as it is all about the outside tollerance, that and the fact they go from what they see so OD.

Pipe is usually cheaper and has a seam where as tube is more expensive and is usually seamless.

For stuff like roll cages I would use Tube but for external bar work I would use Pipe. Both Tube and Pipe need different forma's to bend as a 2" tube has a different OD to a 40NB.

As you are talking external barwork then I would go 40NB Medium wall (3.2mm) and you will be all good.

40nb is bit big for exo cage work... I normally use 32nb medium wall
custom bar work, 4x4 parts, trailers, anything out of steel/alloy :D

I just started a bit of bending myself, just bought a JD squared with 38.1mm die. Its 1,1/2" , then bought some tube. Currently bending 3.25mm and the JD does it with ease. But having the right tools is only half of it, knowing how to use them correctly is the other half. The tube is $17/m, so careful planning is required, not rush into it. But its all fun and becomes easy to use the more bends you pull.
