Dear Ct0517,
there is no argument against your position. Electricity installation is the start of a good system, even if you change some simple issues in a modest system. You discovered a flexible solution. I my case as I was able to influence nearly everything when building the room. My electrican installed three wide cross sectional lead cables in-wall mounted in the 50 cm thick ceiling going directly to the junction box.
I use a specially build passive connector box with many inputs, no filters.
best & fun only
