Check out Nim. I'm using it to build an x86-64 kernel¹ (Fusion OS), and it satisfies a lot of the low-level system programming requirements with an elegant and expressive syntax. For memory management you can choose between ARC/ORC and/or manual. It has two downsides though: small community, and the BDFL can sometimes be rough to interact with.
I, too, have been looking for a unicorn systems programming language, but it doesn't exit yet. Here's what I looked at so far (only languages that don't rely on a GC):
- C: lots of UB, less safe (memory- and type-wise)
- C++: too complex, not a big fan of OO
- Rust: too complex, gets in the way when writing mostly unsafe kernel code
- Zig: Good, but syntax is too noisy; lacks interfaces/dynamic dispatch
- Swift: Doesn't have a good bare metal story
- D: Seems interesting, I may be looking at it (although need to use betterC mode, i.e. not all language features)
- Odin: Game programming focused, small but growing community
- Ada: Strong candidate, but it has too much ceremony
- Pony: I like the capabilities model, but tiny community
- Hare: Also tiny community, lacks polymorphism
- Hylo (Val): Experimental (mutable value semantics), too immature
Thanks a lot for that list ! It matches pretty much what I imagined.
On a side note and coming from high-level languages, D is the easiest to learn IMHO, as it is very dev-friendly, mature enough and has a good interoperability with C libraries.
I considered for a long time nim for its syntax and "low-levelness", but my lack of knowledge in low-level languages made the learning curve too much steep for me. I think I'll switch to it when I'll have more experience.

- Hare: Also tiny community, lacks polymorphism
- Hylo (Val): Experimental (mutable value semantics), too immature
- Vale: Experimental (regional memory management), seems stalled
- V: Good candidate, but mixed reviews on its claims vs. reality
- Austral: Experimental (linear types), tiny community, not much progress
- Jakt: Built for Serenity OS, not sure if it's getting enough attention
- Jai: Focused on game programming, good reviews, but currently closed source (beta)
- Mojo: (Python-like) Seems very interesting and I'd give it a try, but too focused on GPU/parallel programming; also too early for adoption
