It really depends on your output size. If you're viewing an image at 100% magnification and then posting it online, you likely won't need to use pixel-level amounts of NR. It's unfortunate that LR goes from "fitted" view to 1:1 then 2:1 then 3:1 views, which really are a bit over the top. Having a 1:2 view would probably be more reasonable for something like this.

I would try using an output size that you find reasonable for your intended purpose. For web-viewing, 1024 long-edge is pretty well big enough, 1600 long-edge is also fairly good, even big for a good portion of uses.

I hope this may help, as there really is no need to over-concern yourself with the smaller photosites (and as a result denser / higher resolution) of the sensor, trying to keep them smooth over trying to keep it smooth for an appropriate output size.

For similar reasons, print resolution is often looked at from a perspective of viewing distance. If you're viewing it from 10' away, you won't need a 300 dpi print, rather something around 150-100 will be sufficient. If looking at it from a closer distance, you'll want higher resolution. Is either wrong? Not really, it's just a matter of the intended use.

As an interesting exercise, try simply outputting an iso1600 raw image without any NR at 1024 long-edge, review the jpeg and see how much noise you see present. Likely not an awful lot. The larger the output, the more NR you may want to apply.
