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.
I think you’ll be OK but there will be a slightly learning curve since it is a different OS. As for documents make sure they work well with either LibreOffice or OnlyOffice, which should be available on other OSes. There are also always online office suites if needed.
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.
To the Alexa interface?
Closest I found is home assistant voice. This is a link to the hardware but it links the software too Home Assistant Voice
Yearly budget of $200 for any apps I constantly use. I split the amount between the apps. Donate more if I have extra funds.
That’s pretty wild. I honestly haven’t looked at how much ram is used on the computer. It hasn’t been sluggish so hasn’t come to mind. Mostly use a browser, teams, and a VPN.
Its not my machine, so I don’t really care. As long as it doesn’t prevent me from doing the work, then that is the employers problem what OS they want to enforce.
On my personal computer, I run what I want and will continue to do so where possible. Hence, why I like using Linux.
The way apple is now, you would only be able to print (wirelessly) through Apple products. And probably also DRM ink cartridges on a “security” basis.
Old Apple is not the same as current Apple.
