You won’t have more issues with it than you’ll already have using Windows.

You absolutely will, and the ones you get will be harder to solve. It’s far more useable than it used to be, but the overall experience with Windows is still easier.

To respond to your edit: no, you just shouldn’t bring your phone

You can’t harden your phone against every hypothetical because you can’t think of every hypothetical and it’s dumb to think you can. Why would you think you alone can outsmart teams of very well-paid people who literally sit around all day thinking about ways to track you using your phone?

Your phone literally can’t even have signal without your carrier knowing where you are, so why bother bringing it?
