GPS accuracy in the city

I’ve recently been trying to move back to my Forerunner 265 from the Apple Watch Ultra. I live in downtown Boston. Apple Watch Ultra was always spot on with GPS readings (iPhone was never with me, so phone gps wasn’t helping). Forerunner is laughably bad until I get out towards the water and away from the tall buildings. All of the satellite options are enabled. Are any of the more premium garmin watches any better? I use stryd for pacing and distance, but I’d like to have an accurate map of my run.
