I would also recommend openSUSE Tumbleweed. I’m usually a Debian/Debian-based person but I’ve been running Tumbleweed on my desktop for a few years now and it’s been great.

It has a few peculiarities like any distro but it’s been very stable, with few issues even with things like Nvidia drivers. Docs and community seem good too.

There are few if any 10” UPS units available anyway so weight is less of a worry. It’s one of the biggest weaknesses of the 10” system currently.
