Hello! I want to ask few questions about self-hosted cloud hosting.

Which software is the best for self-hosted cloud hosting, Nextcloud or Tahoe-LAFS?

Is cryptomator best for e2ee? If not, how about the software mentioned above?

Any best CardDav/CalDav software? I don't want my contacts to be lost.

Which is the best board for self-hosting "cloud" hosting, RaspberryPi, Odroid, Rock64, RockPro64 or Banana Pi?

If the option in number 4 is RaspberryPi, can I still use Pi-Hole alongside the "cloud"?

Hope you guys can be ask for the questions above!
