Perhaps in the future FreeBSD will have a blocksize/erase-blocksize aware formatting & partitioning tool(s), but at the moment, you need to make sure those are correctly aligned if you want good performance from 4k blocksize drives (& SSDs will probably still need to be aligned to whatever the erase block size is).
