Does your company not just use an automatic formatter? Set a prettier config, format the entire codebase and never have to deal with another formatting change in a PR ever again.
But my issue with formatting, while great most of the time, is that sometimes I want to violate it, and tooling around automatic formatting and format validation is usually installed with the intention that it is 100% correct all the time. Sorry, but as a senior programmer, sometimes it really should be up to me to decide whether code belongs on a single line, and I don't want to fight against automatic formatting or the CI pipeline throwing a hissy fit when I desire that discretion.
On the contrary, as a senior developer you should be able to look at and see the team-wide benefits of consistency. You don't have to handhold new junior devs to learn the style, you don't need to watch their PRs to see if they're being consistent, and you don't need to argue with other senior devs about whether something should be on a single line or not. You just let the automatic formatter do its thing.
Being a senior eng isn't about always knowing what's right, it's about knowing how to keep the team moving efficiently.
