The STM32L471ZGT6: The STM32L4 series ARM Cortex-M4 core runs at 80 MHz. The 1 MB Flash and 128K x 8 RAM support an RTOS and application code.
The EBI/EMI interface lets you attach parallel SRAM or an LCD controller without an FPGA. The QSPI port is useful for memory-mapped external Flash for over-the-air update staging.
The STM32L476ZGT6 is a close sibling in the same STM32L4 series with the same core, memory, and package. The key difference is that the STM32L476 includes a USB OTG peripheral and a crystal-less USB interface, while the STM32L471 omits USB. If your design does not require USB, the STM32L471ZGT6 is a cost-effective alternative with otherwise identical pinout and features.
