Now that goals have been replaced by key events in UA4, I've gone through the commerce modules checkout flow and built some events around the various stages, but  there's a few things I can't work out.

When clicking through the various pages, I can't detect that they've added card details or shipping info because the text of the button they click on at those stages is the same.

Also when I get to the checkout page, nopne of the basket info is iin the datalayer, and none of the css or html attributes on the page let me pull out the cart values into variables.

How have other people got round this problem?

Ive added the latter part there as a bug. It may well come back as needing to be a suggestion, but it may have simply been overlooked there.

In terms of the card and shipping there, its unlikely this will be changed. Simply as shipping doesnt exist in the next version, so that would not be an issue in the first place

Thanks, let me know if you need me to raise it as a suggestion.
