Definitely consider Kubuntu, which is under the Ubuntu Umbrella. Linux has a lot of different desktop environments. I find the KDE Desktop environment is a lot more similar to Windows compared to Gnome, which Ubuntu uses. Ubuntu also has some of their preinstalled applications installed using a package format called snap, which can result in slower startup times for some applications. I think Kubuntu does not. If you don't care as much about having the latest and greatest version of software, also go with the LTS version, which has mostly security updates for 5 years from date of release. If you want to try it out before installing it, you can get an image from osboxes.org and run it in a virtual machine like VirtualBox.
