Passwords I would recommend Bitwarden or KeePass (both of which are in the PrivacyGuides wiki, particularly usefull for KeePass where there are different clients depending on OS)

Email / contacts / calendar I am still struggling on to be quite honest. I am debating right now on Mailbox.org + EteSync OR just using Posteo.de (while it has some security regressions compared to Mailbox.org, it has encrypted contacts and calendar). To be quite honest though the options available in this space are quite frustrating, it is really hard to find a solution that allows for interoperability / data portability as well as E2EE / elevated security.
