I've got an iPad 4 that I use irregularly, so I was a bit slow to update it to iOS 10.3.2. Since doing so, I've found that Safari takes a few tries to start up normally, and, when I try to delete a site from Favorites after accidentally adding it twice, it freezes up for a moment, and may or may not close, but does not delete the bookmark.
Two attempts so far have successfully deleted a bookmark, but in both cases it was the most recent, and not the one targeted. Hard resetting doesn't seem to help.
Frankly, I'm a n00b when it comes to Apple devices, so any advice would be appreciated.

It's going to be very difficult to troubleshoot this based on the info you've provided.
Honestly, the iPad 4 is considered 'old' (introduced in 2012). It does support the iOS version you're using but, like a 102 year-old man, it will struggle with some seemingly basic tasks like putting his pants on and using a spoon, simply because it's old.
If a reset didn't help, your only option might be to buy a new(er) device.
