For passive 3D, the best solution is with 2 projectors on a normal white screen and 3D glasses with interference filters as for Dolby 3D systems.

I think this is the only interference system still available, first invented in 2012 by Omega. Omega 3D Passive 3D System (studio3d.com)

Pricey, but you don't need a silver screen for passive polarization. You will need at least 3,000 lumens per projector, even more if you can get it, or maybe a couple laser projectors. Problem with normal white screens is they usually don't have much more than a 1.0 light gain, and a 3 meter screen (I am assuming a 16:9 screen). 5000 lumens would be best on a screen that size. There are some stretch-canvas screens out there. In fact, Carl's screens has silver 3D screen material that is huge for polarization.

The Dolby 3D system was withdrawn in 2018, but the glasses are still available.

Cost is not an issue.

What is best? Passive or Active polarization? concerning ghosting, brightness and total viewer experience.
