Like some other posters have mentioned, choosing accessory work all depends on where/how your front squat isn't optimal. Have you looked for an instructor, or anyone who is an expert in the front squat? Get one to spot you, see what they say.
If you can't find anyone who's opinion you trust, maybe try filming yourself doing it, and post it here. I'm sure there's a few SFL instructors who can give you some feedback.
