I own one since a couple months ago but I already regret the purchase.
This is me with every single SBC
One is currently running Scripted to integrate my unifi cameras to HomeKit. Zero fans.
I've equipped the other one with 2 beefy 22TB HDDs, Tailscale and Minio. I'll send to my parent's house to act as remote backups.
My notes from that little project are here -

But as a basis for IoT projects that's perfectly fine. They're meant to be install and forget.
Regardless of the Linux distribution, it's still way to early to get good support for RISC-V. Current products are good enough for general development, but RVA23 was ratified less than a year ago, and I don't know of any designs started after the ratification that have hit the market yet. Once that's the case, it should be easier to get universal support, but until then, every RISC-V SBC is a one-off development board.
However there should be next year, and quite likely a couple of different choices by the time Ubuntu 26.04 LTS is officially released.
Waiting until 28.04 for RVA23-optimised code would be far too late.
A good example. There is also a link to builscripts.
Sucked too as I lost $300 but hopefully helps open source community anyway
