Honestly you could easily selfhost all of that except mail and maybe a VPN.
Baikal for calendar. Vaultwarden for passwords.
Privacy has become a very important issue in modern society, with companies and governments constantly abusing their power, more and more people are waking up to the importance of digital privacy.
In this community everyone is welcome to post links and discuss topics related to privacy.

Incoming mail: my own server and my own domain (Postfix). Sufficient to receive confirmation mails and notifications.
Outgoing mail: no good/reliable solution yet. I have to send personal e-mail very very rarely.
Calendar: Tasks.org app, used offline (not synced).
Drive: 1TB external HDDs. GPG encrypted backups of important stuff are uploaded regularly to one of the VPSes I have.
VPN: Tor
Password manager: KeepassXC (with backups at 3 places).
Documents: Stored on computer, important ones are backed up. Confidential ones are stored on an encrypted LUKS volume which I only mount when I need something.
In general things I need on the go (e.g Calendar) is on my phone, the rest is at home at my computer. If I need to move data between devices I simply use USB drives. I don't need no cloud sync of anything.
