Wood rot repair work, balustrade and other

Hi All,
My first post here.

I have a deck where some balustrades are rotting and need replacing. This is work I'm confident to do on my own, but I'm after any advice about quality of timber. To me, it looks like this original timber has either not been prepared properly or maybe not the right grade to begin with.

I've found the "ladies waist" *external* handrail and balusters etc advertised variously, but is there anything I should be keeping in mind when selecting this, to avoid recreating whatever caused this problem?

Secondly, I have found more rot, sadly in some structural elements. These will need either replacing or repair. I've seen some repair work done where part of the timber is cut out and replaced. Do you think I could attempt that here, or would it be better to replace the whole beam / post? The post is most problematic, because it is structural. It could be replaced - it only comes from the deck up, not all the way to the ground. But would it be advisable just to repair the rotted area by cutting and fitting a smaller section of timber? Any advice is most welcome, thanks! (the final image is shows how that post with the rot supports the roof of the deck).

P.s. fortunately none of this looks like termites or pests, it's just water collection.
