Does anyone here do bead crochet? Could you recommend me supplies to get started?

I really want to try out bead crochet, I found a decent yt tutorial for starting and this pintrest board has enough patterns to last a lifetime, but i have absolutely no idea where to start in terms of buying supplies.

Does anyone here do bead crochet? could you point me in the right direction for the correct floss & beads to use? (and also the needed findings, I think each one needs 2 caps and a tube to stabilize it; I have plenty of jump rings and lobster clasps already cos I do chainmaille so that's not an issue) or any other tips would be appreciated too!!
