Is 32GB RAM worth it for heavy multitasking?

Yes — if you actually do heavy multitasking like running a dozen Chrome tabs, Slack, a VM, Photoshop, Spotify, and a video call at once, 32GB stops the stuttering and freezing. With 16GB, the system swaps to disk and slows down. For most people 16GB is fine, but if you regularly push your system, the upgrade is noticeable. Buy it once and stop thinking about it.
