Photogrammetry Experts please help

Hey guys/gals, I wanted to clean up an OBJ/FBX file that was from photogrammetry, now it's triangulated and very high poly so I'll rebuild the geo on top of it so it'll be quads.  The major issue I have is baking the color information from the very high poly mesh to the low poly one I will create.

Can anyone shed some light on how to accomplish this?

Also is there a better way of rebuilding the geo?   (I've looked into zremesher and deicmation master already)

Thanks
