I think the best option for families is either iCloud or Office 365 Family.
I've got both, because I can buy 12+3 month O365 keys on black friday sales and stack them. I think my next bill is coming in 2027. Until then everyone in my family has a 1TB Onedrive account and full Office suite with email.
I use fastmail for personal and o365 for work and if i could gwt work to switch to fastmail i would.... I don't get the allure, especially when you can buy a terabyte on pcloud for very cheap to combine with fastmail.
