I'd pick the late 21st century – somewhere around the 2070s-80s, I guess. A decade or two ahead of my (probable) natural lifespan.
I expect the world to be at least recognisable around that time – not so far into the future that it's purely "sci-fi" or incomprehensible, but far enough to see dramatic changes.
It would be interesting to know if we solved the climate crisis, and to witness our expansion into the Solar System.
Beyond the late 21st century, I think the technological changes would start to become terrifying, so I'd be more hesitant to go any further.
