Home crate vs travel crate?

Hi all, first time poster and about to be new puppy owner here, but confused over crate types and sizes.

For home we envisioned a fairly large crate where our miniature cockapoo/spoodle could move around a bit rather than just kind of sitting facing forward in a small crate on a bed. But I dont think this kind of bigger crate is practical to take in the car for moving the dog around.

Do you typically use two crates and get them used to both? Or is the smaller crate at home fine and its just somewhere to lay? We also got him a nice beg bed we could put in the room he'd stay while we're at work but it wouldnt fit in a small crate, will it be confusing to have a crate with a small bed/blankets inside and a larger bed elsewhere?

Basically, we're a bit confused how it all works and cant find these kinds of details anywhere. Any help would be greatly appreciated, thank you.
