2.5D World of Floating Screens and Camera Shifts

Hi Everybody,

I'm putting in search term after search term but I can't seem to find any good examples, tutorials etc on 2.5D After Effects content that deals with depth, floating/shifting elements etc.

I have to build a world of screens that shifts from one to the next showcasing content. Sizzle reels used to have these a lot like 10-15 years ago. It was what everybody did to showcase content either as floating modules or streams of content they'd slide up and down or do 90 degree camera rotations as the content mildly panned.

Does anybody know what I'm talking about or know of any references I could look at? I'm going at this head on and need all the info I can get in terms of approach, framework etc.

Thanks so much for reading.
