If you have a spare flash drive, you can also test out Linux distros (flavors) before installing them in a live mode, like a demo.
Best of luck.
Can also check out Nextcloud. Yes, its more overkill than just calendar and contact sync but its not that hard to set up and self-host. It has an interface for you to fix your calendar and contacts graphically and works well with DAVx5, if on Android. Believe you can just add the CalDav and CardDav for iOS, but have not tried it personally.
