Rooftop solar doesn't only need to be on residential buildings, it can also be on industrial and commercial buildings, which take a significant land area.

One last benefit of most renewable energy that is related to its distributed nature: it's easy to slowly roll out update and replacements. If a new tech emerges you can quickly change your rollout plan to use the new tech, and replace the old tech a little bit at a time, without any energy disruption.
With mega-projects like nuclear reactors, you can't really change direction mid-construction, and you can't just replace the reactors as new tech comes online, because each reactor is a huge part of the energy supply and each one costs a fortune.

Also, according to the doc you shared of land-use, in-store wind power is nearly the same as nuclear, since the ecology between the windmills isn't destroyed.

So while I agree that nuclear absolutely has a place, and that renewables have some undesirable ecological repercussions, they're still generally an excellent solution.

The elephant in the room, though, is that all the renewable solutions I mentioned will require energy storage, to handle demand variation and production variation. The most reliable and economically feasible energy storage is pumped hydro, which will have a similar land usage to hydro power. On the upside, although it has a significant impact, it does not make the land ecological unviable, it just changes what ecosystem will thrive there - so sites must be chosen with care.
