Alpine Linux: uses musl and busybox by default. Extremely lightweight. Some things will not work
I use it daily, which things won't work? Honestly it's "just a distribution", you'll have the same experience with it as OP has with Arch.

I ran transmission and WireGuard for ages before I recently switched my server over to x86, worked fine?
Idk about Sdkman though, I don't do Java development, but if it's written in Java itself I fail to understand why it wouldn't work 🤔
