I have a LINHOF studio stand, a monopod on a triangle shaped foot on wheels. There are two removable columns that can be cracked out over 2 meters high and be mounted in different modes, and can easily hold a heavy linhof Kardan optical bench camera.
It's the former model in beige colour and chromium elements and a plateau to put on the accessoires while shooting.
It's still in rather good shape as it is extremely well and heavley built the German way like a Krupp crane...
Here you see how I used it in my studio while shooting archaeological artefacts digitally for (multiple-) exposure blending:

I have some angle connections too.
The wheels, these ware mounted later, have rubber band and built in brakes, I think they wouldn't harm the pavements in you studio, it did not happen in my studio...
I was thinking about selling it (without the camera) but it's so heavy, over 60 kg, that it can hardly be shipped.
