As I’ve stated in my earlier comment I’m getting no issues & using Safari on a new iPad, a new Mac M2 & a slightly older Mac M1 with a complete wipe & OS Ventura re-install.
The iPad is just a few weeks old, the Mac-Book M2 a few days & the Mac-Book M1 wipe & re-install of Ventura only done on Sunday. There was nothing to carry over to that M1 unit either, my wife never having used a unit previously, or ever having previously expressed much interest.
Basically when I was considering an upgrade she asked if instead of me P/X ing my M1 unit if she could have it instead. I’m not sure why the interest now, but the point is all units are bang up to date on software, with totally clean & unmolested installs & all functioning perfectly.
I’ve also just tried my iPhone SE on the dashboards. Once again that’s using Safari, Private Relay & with it set to block pop ups. I don’t usually use the browser at all & had to set it up to do so, but again & just like with the 2x Mac-Books & iPad I’m personally not encountering any issues.
