If “to get the machine to do exactly what you want” is an important goal, I'd recommend C or C++. Those are well known tools for those purposes. FP languages are rather about getting more ideas from math into how you structure your code.

I don’t think you need to go that low level. I find it much easier to optimize around things like memory layout, allocation patterns and cache effects even in Java and C# compared to (essentially) any functional language.

I think this is just a feature of imperative languages over functional ones. Functional languages are excellent for many things, but not for this stuff.

Where should I look to learn about doing those things in Java? Last time I tried looking for guidance I mostly found people saying it's not worth the effort since the JVM JIT will do better.

This thread is for people who are smarter than compilers. Java is not different from C in that regard.

Rust on the other hand is zero-cost abstraction but pushes you to write functional code.
