Thanks for the guide! Very straightforward process. Took me somewhere between 45-60 minutes to complete. The hardest steps were loosening the grippy facade from the back of the chassis and desoldering the old microswitches.

I ended up using Kailh GM 4.0 switches as replacements based on a recommendation from the reddit thread that led me here. They're nice and clicky.

Also, I found I could simply press the adhesive sliders back into place at the end. To remove them, I used the very thin spudger shown in the photo for Step 9 to slowly and carefully release each slider and adhesive from the chassis underside, making sure the adhesive remained attached to the slider, and being careful not to touch the adhesive with my fingers or get it stuck to anything else. That seems to have done the trick, as I've had no problems with the reapplied sliders so far!

While you're here, you'll want to disconnect the ZIF connector directly opposite from this one, which can be seen in the lower right of these photos, nearer the camera cable connection points. The guide doesn't mention removing that cable, but you'll need it removed before you can lift out the motherboard.

It's probably best to remove the microSD card reader at this point. The guide never states to remove it, but it eventually disappears from the photos. Two T5 screws are all that are holding it down. Easier to take those out and remove the assembly than to try to remove the EMI shield underneath while also holding the ribbon cable out of the way.
