Compiled Java is still cross-platform. It’s been a few years for me, but when I last worked in C# it was a giant PITA to work on it in Linux or MacOS. I hope it’s gotten better.
.NET (not .NET Framework) is cross platform and can be compiled into native binaries on a variety of platforms. There is however the wrinkle of not all the libraries within .NET being supported on all platforms. Most notably, everything involving a graphical UI is Windows only.
The most well known cross platform .NET project you probably have heard about is Jellyfin.

TIL, I love jellifin
Modern .NET (i.e. .NET Core and later) is cross platform. In fact, .NET APIs now are routinely run in containers not based on Windows.
