How to install a shallow electrical light fixture box in front of pipes with minimum effort.

You can find the shallow box here:
ARLINGTON FSC405R Sconce Box, Diameter: 4", Non-Metallic a.co/d/coCPqIR

Can this be used for ceiling? Trying to mount ceiling lights but there's a beam where I wanted to use a regular junction box.

I think so, same principle, just check weight limit. I bought it on Amazon.
