If you’re working with time series data and using a vectorized algorithm implemented with SIMD instructions you can achieve decompression speeds approaching 15

If you’re working with time series data and using a vectorized algorithm implemented with SIMD instructions you can achieve decompression speeds approaching 15 GB/s [1]. Anecdotally when working with biological signals at my day job, compression is a massive win and an absolute no brainer tradeoff when shuffling data across the network or even just storing in memory. That said, I think your first point is still reasonable for certain types of data and compression algorithms.
