i pay $20 a year for basically all of that and even more stuff but open source provided and maintained by a local server company in my country. of course i don’t use half of their offerings because some stuff has alternatives more suited for the platform or its simply not needed. but e.g. their service offers nextcloud which has most of the stuff you listed bundled into the platform by default. and then they have another 50 services added on top available for use.
