Checkout Nextcloud calendar and appointments. If you host your own, you have full control of what apps are installed on the instance. Most Nextcloud subscription services come with calendar + appointments pre-installed. You will need a mail server or relay configured to confirm appointments with people. Easy appointments is an alternative server app you could deploy which does just appointments. Nextcloud provides a ton of other things which you might like to have as a freelancer.

It is a question of whether you really need all your traffic going through a VPN. Your app might support split tunneling. VPN browser extensions such as Proton, Mullvad, and Brave will only route that browser's traffic through VPN. Since I am running Linux, a DNS resolver and am generally off of most corp and government servers, my need for VPN is more limited. I activate ProtonVPN extension in Librewolf browser where I open news sites. I use other browsers without VPN for safe stuff such as my own and friendly fedi sites to get full bandwidth. I use split tunneling on Android to similarly exclude safe apps from VPN for a private and efficient setup.
I have a similar 321 strategy without using someone else's server and needing to traverse the internet. I keep my drive in the pool shed, since if my house was to blow up or get robbed, the shed would probably be fine.
It costs a few bucks more per month than services such as voip.ms, but it is simple and stable. I wasted a lot of time aligning different VOIP clients with voip.ms which I never need to do with jmp.chat. If you are novice, go with jmp.chat to spare some headaches.
The client app is FOSS other than the Google blob for notifications. The server SW is partly closed source because they say that is needed to prevent spammers.
