First of all, credit goes to IDGeek121. I found this trick looking for a fix for audio lag in 1080 Avalanche, and on the game compatibility support wiki, this user mentioned disabling all logs for a nice speedup. Sure enough, 1080 went from dropping to 40-45 FPS, to almost perfectly constant 60 FPS.
Interestingly enough, I also want to point out that I was having issues with even more common games having slight audio pop, lag, etc. When starting Mario Sunshine, I recall almost always a quick audio lag somewhere between loading the game and starting up a save file. I recently got into The Last Story and Xenoblade Chronicles as well, and while they didn't give me any severe audio issues, they had a similar audio pop/lag that barely occurred, but was noticeable. Disabling all logs fixed the issue.

My only guess is that one of the chat logs are being filled up really quickly. Perhaps this is an issue the developers could look into?
EDIT: attached image to show anyone curious how to disable logs, or the log in particular (I'd say turn them all off unless needed for diagnosing dolphin issues, but remember to turn them on if you have any other issues.)
