I do a bit of this for art and electronics related stuff.
When I'm using a cellphone or a light weight M43 camera I use a bembo trippod - they're not cheap, and I wouldn't trust mine with a heavy camera.
This is basically the same thing

For anything more serious I'd go straight to C-stands with cross rods, magic arms, sandbags and so forth. They're much heavier, more stable, more flexible and cheaper than similarly capable tripods.
This setup
LINK is ok, but I would strongly recommend putting a heavy sandbag on the base, and possibly even attaching it to the edge of the table as it's super easy to kick a c-stand when you're moving props, and when they fall they come down hard.
I would personally want to go with two or three c-stands linked with rods, sandbagged, with proper tripod heads for cameras and magic arms for lights, microphones and suchlike. By the way - Don't use a spigot to hold your camera, use a proper tripod head, the spigots can easily damage the tripod mount, they are made for accessories, not for cameras.
The biggest advantage of C-stands is that you can set them up to also hold lights, secondary cameras, microphones, and suchlike.
The big disadvantage is that they tend to being fairly permanent installs - You wouldn't want to set up and take them down too often.
The ultimate is a proper overhead studio lighting rig like this
LINK, but if you don't have a spare $10k or so burning a hole in your pocket they're not really worth looking at (I used one frequently when I did my masters degree, I miss it).
