The 48-UFQFN exposed-pad package (7x7 mm) keeps the board area small, but the thermal pad needs a via stitch to the ground plane if you plan to push the I/O current or run the core at full speed near the top of the temperature range.
No — it has an internal oscillator, so it can run without an external crystal for most applications. The clock tree also accepts an external source if you need tighter accuracy.
Both are 64 MHz Cortex-M0+ MCUs with the same Flash and RAM. The G041 adds I²S and a 19-channel 12-bit ADC versus the G031's 12-channel 12-bit ADC. Pin compatibility depends on the package variant — check the STM32G0 reference manual for the exact footprint mapping.
