how do yall handle client selection phases

i just started out doing grad pictures for college students, i've come to realise photographer's pick ≠ client pick.

so i wanna let clients pick some favourites before i fully edit the gallery, but i also don’t wanna accidentally give away the whole gallery/raws for free.

do people usually just send low res watermarked proofs or use something like pixieset? curious what workflows yall use
