Personally, I use Rocky Linux on my servers. It’s stable, and has plenty of support since it’s RHEL-based. It’s supported until 2030 or so, and it doesn’t have any of the cloud-init or netplan stuff that Ubuntu Server has.

It’s also pretty simple to set up docker/podman containers, although you need the EPEL for podman-compose and for a lot of other packages, but once you get your setup the way you like it, it just keeps running and running.

I’m not sure about how private it is, but I use Ecosia for my search engine. It works great for me, and the images are alright. They are pretty transparent with their privacy, and you help plant trees too!

Some great newer tech distros would be Fedora Silverblue, or if you like Debian, there is VanillaOS. They are immutable distros, and they introduce a new way of using Linux. I like to pair it with distrobox, which lets you use regular Linux applications in a container.
