I recommend you consider Rust if you can. I'm not going to lie: it's definitely harder to learn than Go, but the benefits are immense as Rust is serious about C-level performance and encompassing the ample capabilities of C++ while bringing some very commendable goals (ie safety) into the binary-compiled language arena.
And believe me: once you pass the first slope of learning (borrowing, lifecycles...), everything clicks just right and writing code becomes a very delightful experience, similar to what you do with [pick a trendy dynamic language of your choice].
And I think it's safe to say that Rust in 2023 can be considered mature and non-niche.
If you'd like sheer enthusiasm to help you make your mind, I recommend this guy's YT series on Rust:
