A lot of times, you can get access to IP blocks. You can view a reference design of what the module does but the actual code is a binary blob owned by the chip manufacturer. You can treat these as functions and build larger designs from them. It's great because you don't have to write really low-level stuff like RTL except for hooking up the different modules. You can then do some more complex combinational logic using always blocks that kind of look like C. It's not super high level like C++ or python but you can get some higher levels of abstraction. Some IDEs have a visual way to write the code using schematics. You connect the logic modules together using wires. It makes HDL a bit easier to understand what's happening but you need to compartmentalize your code as much as possible, essentially making everything a function.
