D&D 5E - Throwing Enemies Against Walls
I think how mobile/engaging/cinematic a given combat is depends a lot on your vision of that scene as DM and the details you communicate about it.
For example, when the PCs were in old ruins, I described the dilapidated quality of the stone practically toppling over since the mortar had long since eroded and past structural damage had weakened any dry-stacking/locking that once had kept the stone together. IOW, I strongly foreshadowed: "You can topple these stone walls."
Sure enough they exploited the heck out of that.
Another example, I'm designing a dungeon which has an oil reservoir running through some of the halls. Basically this is a grooved alcove running the length of the wall with a shallow trough holding lamp oil. Lighting the oil causes the surface to burn providing illumination. A creature pushed into one of these walls would likely get oil covering a limb or their face.
As DMs it's easy for us to imagine the scene because either we've created it or we have the module in front of us. For players it's more challenging. So it's incumbent on us DMs to articulate the scene super clearly (which probably feels excessive/boring from our standpoint as DMs given what we already know, but actually is necessary for most players to grasp the scene).
