Do I need to learn MCU to consult an expert in electronics?

CPLD and FPGA are SIMD architecture, and single chip microcomputer is SISD architecture. They have their own advantages, for example, single chip microcomputer is suitable for logical judgment and circulation, while CPLD and FPGA are suitable for parallel computing and large-scale convolution. It is generally believed that single-chip microcomputer is relatively simple, low-cost and interesting for some simple tasks, so I suggest you learn single-chip microcomputer. Because your work may not often use single chip microcomputer, so I think you should learn 5 1 series. If you are interested, you can learn some advanced single-chip computers, such as Freescale's S 12 series and so on. You don't need a single chip microcomputer. Like all the basics you have now, you can learn by yourself. Go to Baidu, Google, there are many tutorials.
