When you do intuitive F2L enough, you'll generally know what cases are very slow for you, i.e., ones that require a lot of moves or require a lot of repositioning your fingers. I'd just recommend browsing each algorithm, and then use one if you think your normal approach is horrendous at the case. A good example would be keyslotting, since it's so slow to have to pull out a piece, combine it, and then put it back in.
