I had a similar issue when I started with Hyprland to set up all the additional programs which usually come with a DE. But there are preconfigured setups which give you a “full DE” experience out of the box and you can customize from there.

I recommend SolDoesTech or My Linux for Work. Both have full guides on Youtube as well for “easy” Arch + Hyprland installs.

And sc-im for spreadsheets

I had a very similar experience when I switched to Linux around 2 years ago. Now I dread every second I have to use Windows at work.

You can block it’s internet access, but I don’t know if you would still get all features.
