Email: basically forget it, email is inherently non-private because its privacy depends on the other person's provider (usually google), not just your own. I use fastmail if that matters. mxroute.com is there if you want cheap and DIY.

Drive: nextcloud? I use Hetzner storage box and sshfs but they have a "storage cloud" (nextcloud) product too.

vpn: openvpn, wireguard, ?

password manager: use the one built into your browser. If you need a password on two separate devices but it's not too many passwords, just type them on both. Beyond that maybe sites should start allowing you to have more than one password, or browsers could let you export a password through a qr code. Having passwords on a separate server is a total head scratcher to me in terms of security.
