Dynamic DNS doesn't reveal your IP to anyone that doesn't know the domain name. Most self-hosted services also have offline modes. e.g. my finamp playlists are synced to my phone when I'm home and then play offline anywhere else. Within your home if your Internet connection goes down, a self-hosted service (e.g. streaming video) has better availability than cloud ones.

That assumes you don't set up SSL, since cert transparency now forces the publishing of every hostname that a cert is issued for.

(Painfully) work-around-able though, with a paid wildcard cert and manual setup, or with a self-hosted certificate authority that you have to install everywhere.
