If I can't call anyone because the contacts are not synced with iPhone, than keeping contacts @gmail, e-mail @protonmail and storrage @synology is a messy option.
CardDAV (as well as CalDAV) is a must!
And for real, contacts doesn't have to be encrypted.. we don't call NSA people or something.
Security is a great thing, to much security = lack of features/functionality = people don't switch.
Like in my organization, forcing users to have a complex password every 3months and guess what? Full of yellow post-it pinned all over the desks :)
