Just to be clear, if you post "usage" I can't take you credibly. You can only really discuss your hardware RAM amount and your "Memory Pressure" from Activity Monitor.
Because of how macOS manages memory on Apple Silicon, raw "Memory Used" numbers aren't enough to understand your system's ability to perform well with a given workload. Instead, "Memory Pressure" is the primary indicator of how effectively your system handles workloads given the available physical RAM.
