Steel was original, and what I would be inclined to stick with.
One problem with "copper" is that nothing is really made with pure copper.
And what alloy you get is important to things like resistance to work
hardening (which can lead to cracks) and so on.

The size isn't critical, just whatever works easily with your connections.
IIRC the original line on a 4A was about 3/16" od and had push-on fittings.
I did use copper there (alloy 122 I think) because I couldn't easily source
steel line in the right size for my TR3A (with 1/8" compression fittings) at
the time. Now I believe the usual suspects carry it.

That was standard equipment on the early cars, but the valve was mounted to
the frame and had a hard connection to the line to the tank (so you could
turn the valve off to replace the soft line to the pump). Seems like a
great idea to me; not sure if they discontinued it to reduce costs or
because the valve they used was more prone to leak than anything else <g>
