Compatability is similarly a non-issue as none of the formats you mentioned utilize DRM, and tools are available to freely convert from one format to the next. However, if given the option between a closed format like ALAC and an open format like FLAC, choose FLAC every time. The only reason to use ALAC is if you're forced to by using a closed application like iTunes, and if you're actually using iTunes I would strongly encourage you to consider exploring better options. There is no reason on this Earth to use iTunes in 2018.
