Manjaro is an easy to use Arch Linux distro, you can benefit from a large collection of free and non-free (be careful..) community built packages with the AUR package manager.
Linux Mint is a downstream distro from Ubuntu, with some useful add-ons, it has a less corporate feel and more community based. You can download the most lightweight desktop environment with it XFCE. It also doesn't use the snap package manager by default that is considered less safe.
