Broken digitizer or something else? Should I even be attempting this?

Hi, hope the format is right.

I've had my S8+ since 2017 and had no issues other than two small dead pixels until last month. No warranty anymore unfortunately.

Firstly, my charging port 95% of type-C cables, not recognising them so I’ve been using wireless charging – bit of an inconvenience but not that big of a deal. and manageable.

However, I’ve dropped my phone two weeks ago or so, everything was fine until yesterday (other than slight cosmetic damage). Overnight my screen has been acting weird, I did the Samsung diagnostics test (*#0*#) and a small horizontal bar down the middle (close to the crack, roughly 1.5cm wide) has fully stopped working. Phone is still usable, but a massive inconvenience. From my research it looks like the digitizer has died, just wanted to confirm if that’s what it looks like. In the UK there are no repair shops open due to the lockdown and going to the post office to send it off would be really out the way for the next five weeks minimum. I found replacements online for roughly £25, and considering of attempting to fix it myself.

I think I'm capable of following instructions from YouTube as to how to fix it, otherwise my I'm limited as to what I can do (e.g. apps that require the whole screen) during the lockdown.  I just wanted to see if it’d be stupid of me to do so, I’ve done minor repairs on phones before (like replacing the charging port on my Note 4 couple years ago and had no issues) but never the screen itself. Just wanted to see if it’d be worth my time doing now, or even attempting to repair it myself. Getting a new phone isn’t really an option, at bare minimum until November/December so need to work with what I have.

My second question is, if I was to attempt fix  the screen (at my own risk), while disassembling whether I should replace the charging port and get it out the way, or whether I should do everything on its own: see if the screen works and then re-open and only then replace the port?
