However the notorious charging port ribbon cable seems to have broken again and this might be some of the last things I write with the phone :(

Yeah, that is one annoying issue for sure.

It happened to mine as well, what I did year (years?) ago, was to use a tiny piece of electric tape in the flex to make pressure and make it to recognize the charger as well…

Still working fine after that.

If your device stops recognizing data I think it is game over though.
