Fedora is the distro you want. It's not bleeding edge, but everything is up-to-date and the kernel is 1-2 releases old. It has a 6 month release cycle and 13 month support window iirc.
I find it a lot more stable than arch and Debian Sid.
I use Fedora with dnf automatic[1] on all of my machines. Only problem is my Desktop PC, which has a nvidia gpu with the official nvidia driver installed. Every few weeks there is a new kernel version which often only works with the brand new nvidia driver version. I use grub to choose the previous working kernel version until I take the time to download and install the new nvidia driver.
