Figma lets you select a whole bunch of objects with the same characteristics.
Move Layers to Top
or Bottom of Stack
The previous keyboard shortcut, with the addition of holding a modifier key (ALT or SHIFT depending on your platform) will move an object to the top or bottom of the stack.
Paste Object Directly Above a Layer
If you already know exactly where in your layer stack you want an object to appear, select the item that you want your new object to appear above then paste in your new object.
