Linux LTS if stability is the most important. Realistically, "normal" Linux works for for it too, not sure you have to care as deeply about what kernel you use as you seem to do.

On my desktop I use linux-cachyos-bore-lto which seems to give me a slight performance boost in compilation times compared to the regular kernel, but I've had at least one crash that I've unable to attribute to any other specific issue, so could be the kernel I suppose, I wouldn't use it on a server nonetheless.
