I mostly use them for really simple things like hovering the cursor over something to show a tooltip, or navigating menus in DRG and the inventory in Minecraft.

I realized how much I miss this hybrid approach when I had my 3 month long Genshin Impact phase. Genshin does support either Keyboard and Mouse or controller input, but not both at thw same time, and the menus suffer from mildly inconsistent UI and UX.
