Yeah this sounds like way too much maintenance overhead. I've opted in for a middle ground: I don't use FAANG/MS for anything critical and choose other hosted solutions instead.

Posteo was already mentioned, Mailbox.org is also nice for E-Mail with an own domain. I only had to set up the DNS records once and rarely have delivery problems.

Nextcloud doesn't need to be self-hosted either, there are many good providers.
