Riley Brown recently shared a tip for adding soft body physics in Blender by applying the simulation to a lattice instead. While this isn't a brand-new trick, Blender 5.0 introduces the Lattice Deform Selected feature, which makes things much easier.

There's also a new video by Jan van den Hemel, known for his book Blender Secrets and popular quick tutorials, which will teach you all about Lattice Deform Selected:
