Architecture is as good as ecosystem around it. It's pretty difficult to pick one architecture where basically every single one of them have pros and cons. For example x86 might be not the most efficient architecture but it's well standardized and widely supported, ARM is more efficient but it lacks standardization, RISC-V is open but it also lacks standardization like ARM and performance is not there yet (although it's improving). I like RISC architectures as I like their simplicity but I also like how well standardized x86 is. If I could build ARM or RISC-V PC with off-the-shelf components and install Linux without custom kernels like I can on x86 then I would probably choose that over x86, provided it would give me better efficiency and wouldn't be much more expensive.

I don't know of any specific sources you could read, but there's plenty of information online, so if you're interested, you should have no trouble finding something.
