So my car has pretty much been a rattle fest for the past couple of days. I found three sources of noise and (hopefully) fixed them. I used electrical tape, paper tape and 1mm thick felt tape as well as plastic pry tools for removing trims.
1. Rear view mirror and camera housing
I identified the first rattle coming from the rear view mirror housing thanks to @TypeRGirl. I took it apart, including the larger plastic bit of the camera housing. You can watch the first couple of seconds of this video to see how:
I noticed that the clips holding it where kinda loose on their own so I took them off and put some tape underneath, which fixed them in place.
Then I applied some black tape all around the edges of the plastic housing behind the mirror. I cut it so it's not visible when put together. This seems to have stopped the rattling coming from there.
2. Center display
I noticed occasional rattles coming somewhere from the center of the dashboard. I put my hand on the display and it stopped. I let go and it started again. Then I found this thread describing exactly that issue:

You can find a PDF in that thread with instructions on how to fix it. Apparently it's a TSB for the 2022 Civic but I decided to try it on the FL5:

Essentially, you need to remove the display and place some felt tape underneath it. To do this, I removed the dashboard center trim to reveal screws holding the display. I watched the start of this to see how the center trim is removed:
Be careful here. I put a small dent in the foam around the trim while doing this. In retrospect, it might have been possible to get to the two bottom screws with a wrench from the top (when you remove the plastic cover behind the screen) without removing the whole center trim. You don't need to unscrew them completely since the screen can slide off once you loosen them. I did it the way it was described in the PDF though. There are two more screws you have to unscrew from the top behind the screen though. After that, the screen is only clipped at the bottom.
You can disconnect the hazard lights switch as well as the start button if you need more space, but do not disconnect the climate controls. I figured if I don't disconnect it, I won't need to do step 6. in the PDF "Do the climate control unit Self-Diagnostic Function with the HDS" (and to be honest, I'm not exactly sure how to even do that). The AC has been working fine once I put everything back, so I guess it worked.
The red circles is where you need to apply the felt tape (not yet done in the picture). There is already some on it but apparently not enough. Make sure it's not visible after you put the screen back. The PDF shows exacly how much and where to apply it.
Once I added the felt tape and put everything back together, I also decided to put some felt tape on the back of the display where it connects to the plastic cover. I used the front camera of my phone to look behind the screen since it's hard to see back there:
Not really sure if this was necessary, but it made me feel better. So far, no more rattles coming from the screen.
BTW: Really make sure that your rattle is coming from this exact place before you decide to do this, as all of my rattles sounded like they were coming from somwhere in the middle but really weren't. It's quite tedious and you might break/damage/scratch something.
3. Plastic trim in the passenger side footwell
While driving over bumpy roads, especially in R+ mode, I noticed a rattle that sounded like it was coming from somewhere inside the dash again. I was able to reproduce it in my driveway by lightly bumping the dash with my fist and found that the noise is coming from the passenger side footwell. There is a big plastic trim down there around and behind the knee airbag. I took it out (it's clipped so just yank it a bit) and placed felt tape all around the edges. It's quiet now.
I didn't take pictures of this but it's relatively straight forward.
It's a longer post but I hope it helps out someone out there. The reason I did all of this myself is that I really don't trust the dealers around my area. If you're satisfied with yours, by all means let them do it ?
For now, everything seems quiet the way I expect it to be. Hopefully it stays that way.
