OK. after several tries, I figured out that I have to include both

setuptools

and

wheel

in my

[build-system].requires

list. Otherwise I get errors about

error: invalid command 'bdist_wheel'

. So, I’ve got my metadata in pyproject.toml, with

generate_setup = False

on my

python_distribution

which is working. But none of the metadata from

[project]

is making it into my wheel. Turns out I have to have setuptools 61+ to use that. So, now I’m working on updating my build-system.requires to make that work…
