If you use auto WB, a reference shot won't really help jpegs as each shot will be different so you'd have to set the WB to incandescent or something for consistency, then you might as well do custom & not have to post process.

Personally, I am not too keen on shooting grey cards and setting the
in-camera white balance, as it is too easy to forget you have manually set the white balance.

True but that approach really does work well indoors. Post processing is a hassle. The idea of shooting a slightly blueish white card is clever. You could do this after the fact in the same lighting for spontaneous candids when you don't think to set a custom WB & maybe get some use even with auto WB.

Rather than carrying a variety of tinted gray cards around, would it
not be easier to use a white card, bit of paper, or any other handy
white thing in the image (or snapped at the same time under the same
light) as the initial white reference, and then simply nudge the
colour temperature or tint a bit on the editor?

Sure. The tinted card idea makes sense if you wanted the jpegs to come out right with no photoshopping or wanted precise matching from one shoot to the next. The only time I bothered setting a custom WB in the camera was shooting a sculptor's work with a gray backdrop paper he had set up. Those went on his web page and if I come back to shoot newer work, I can have those match side by side on the web site by repeating with the same piece of paper. Plus I didn't want to second guess the artist's colors: let the camera figure out what neutral gray is. I shot raw + jpg but only needed to bother with the raw files for a few tricky exposures.

With raw, i's a breeze to apply a custom WB to a set. With a jpeg you'd have to do the levels eyedropper, then save that out to a file & load it back into each... lotta work.
