Mail and calendar: i think mailbox and posteo should work well, they both support IMAP for mail and CalDAV for calendar, just get a nice client(surprisingly not many for calendar standard protocol. thunderbird on desktop and etar/fossify calendar on android. stock one on ios)
VPN: MullVAD is the best
Drive: Check filen, it’s cheaper and better, and has powerful CLI tools
Pass: Maybe unofficial self hosted version of bitwarden. It’s called vaultwarden, and don’t be afraid of selfhost, basically all you need to do is docker compose.
Which lemmy client is this? It looks very nice
