LZ4 has branchless decompression, and lower cache footprint, thus it can work on low end, and non-desktop CPUs equally well.

zstd, brotly, snappy were seemingly all made with high end x86 capabilities in mind.

I also appreciate LZ4's simplicity and tiny code footprint.

zstd is brilliant as well, but in terms of code base it's a whole other beast.

Yes decompression on baremetal cortex m4 is a mere hundreds of bytes, you can decompress it from flash directly to its output buffer.

I've used it in bootloaders that have slow transfer mechanisms (uart, i2c) to get whatever speedup I can for a few hundred bytes of binary.

Google snappy is same class as lzo and lz4, not same class as brotli and zstd.
