Building a new OS isn't going to make RISC-V boards faster. The primary limiting factor here is the actual hardware.
Kubuntu, because it's the most solid distro I've used that meets my needs.
The memory isn't really doable with this SOC, but the storage is just an SD card slot on the motherboard. (I saw this and spoke to the CEO at this year's Ubuntu Summit.)
I started on 24.04, but I updated to 24.10 to get Plasma 6. I quite like snaps (enough so that I publish the snaps of several tools)
I'm very happily using Kubuntu on mine.
Why? It works with both Ubuntu and Fedora, so making images of other distros should be pretty straightforward.

Containers are great, but I find Docker's way of making container images to be pretty bad, personally. Fortunately you can use other tools to create OCI images and then copy them into Docker, as the runtime is pretty nice for dev machines.
