Probably on the side of your project, but did you try SmolBSD? <https://smolbsd.org>
It's a meta-OS for microVMs that boots in 10–15 ms.
It can be dedicated to a single service (or a full OS), runs a real BSD kernel, and provides strong isolation.
Overall, it fits into the "VM is the new container" vision.
Disclaimer: I'm following iMil through his twitch streams (the developer of smolBSD and a contributor to NetBSD) and I truly love what he his doing. I haven't actually used smolBSD in production myself since I don't have a need for it (but I participated in his live streams by installing and running his previews), and my answer might be somewhat off-topic.
At a glance, it's a matter of compatibility, most software has first class support for linux. But very interesting work and I'm going to follow it closely
