At my wit's end trying to diagnose and troubleshoot my device...?
I can't be certain that the current buggyness (clicking anything on the screen, whether app related, system setting related, anything is excruciatingly delayed, often requiring multiple taps before there's any response) is a direct result of having installed an apk from APKUpdater, but I would not be surprised.
Can anyone advise on steps I can take *before* the last resort of doing a hard reset?

I've been in the modding game since the Galaxy S3. Unfortunately, I can tell you it's not worth troubleshooting from what you're describing.
Whenever you mod, you need to have a backup solution in place at all times for stuff like this where you don't even know where to start troubleshooting.
Look into Swift Backup for your apps or TWRP Nandroid backup for a full 1:1 backup. For now, you'll likely have to bite the bullet and reset your device.
