I'll keep my WhatsApp account, but I pressed "Not Now" and am currently in the process of manually deleting every chat, all media, and exiting all groups on WhatsApp and instigating the chats anew on Signal. WhatsApp will exist only so that those who try and reach me can do so... but I'll only actually chat on Signal.
You're almost certainly on this, but don't forget to also deny whatsapp access to your contacts.
