I quite like the option of being able to program in a more functional style in C++. If you have the cycles to spare, or a sufficiently smart compiler and it allows you to say more with fewer keystrokes and better readability then why not? I haven't used it yet, but C++ Streams[1] is a header-only library that appears to have great ergonomics and an API that will feel familiar for those who know Java Streams. Since I haven't had the luxury of being able to use C++20 yet, I was unfamiliar with the ranges library. Starting at 1:06:00 you can see some motivating examples for those and they look great to me. Much easier to read than the equivalent STL. The libraries mentioned in the video TartanLlama/optional[2] and TartanLlama/expected[3] clearly demonstrate the value proposition (brevity and clarity) on their github pages.
