The answers to the linked question address two technical problems, angle of incidence and polarization associated with specular highlights.
You should also worry about the clouds, they are way too overexposed and you can't recover details in post.
Here's the aesthetic part that answers the last part of your question:
Shooting landscapes when the sun is high in the sky is generally NOT a good idea. You will have these specular, shiny highlights on water you can't fix (unless you use clone stamp to erase them altogether in post but that's messy).
If you want to shoot pretty landscapes you have two choices of time for far superior light, sunrise and sunset. Both these have these 3 phases
Blue Hour (comes before sunrises and after sunsets) - sunrise - golden hour
Golden hour - sunset - blue hour
For every location these times can be calculated so you can plan your shoots. apps like Photo Time can help.
Blue hours are the best for diffused, colorful, soft light that elevates the mood. Sunrise and sunset cast soft, directional light with amber tinge that brings out texture on surfaces and lights up areas you don't even notice at other times of the day.
If you shoot the same landscape at either of these hours, you'd junk the picture you posted here, it'd be that different and that good.
