I don't get why this is a big issue. This isn't some recurrent decision to be made. It's something a lead decides once and the project follows. That's it. Many companies have style guides anyway (eg Google[1]); the choice of a formatter is much simpler.

Because at some point you have to interact with some other team or project that made a different decision. And whatever you picked might fall out of favor and lose support. There's already a graveyard of Python type linters, including Google's pytype.

Especially the uv thing. You clone some non-uv git repo that has no pyproject.toml and you don't know what to install. Maybe has requirements.txt but it's partially wrong.
