I'm thinking that your best bet might be to simply replace your 4 way
switches with ones that have either lighted toggles or toggles of a
different colour than the rest of the switches in each "bank" of
switches. That will at least set them apart visually, so you're brain
recognizes that those switches are different, and the toggle being in
the up position doesn't mean that anything is "ON".

I'm not familiar with 4 way switches, but with 3 way switches there
really is no "OFF" position like you have with ordinary switches. With
3 way switches, you have two different "ON" positions where the switch
sends power down one conductor or another depending on the toggle
position, but no "OFF" position. But, in that case, toggle down doesn't
mean the light is off since whether or not electricity flows depends on
the position of BOTH three way switches, not just the position of one
three way switch.

This is how they are wired. Beware, different terminology to USA.

The second 4-way circuit is kind of like a California 3-way with a 4-way
switch added. A California 3-way is very useful in very limited
applications. Harry's circuit does not have the useful features of a
California 3-way.

A simple 3-way is easy to troubleshoot. IMHO this is a monstrosity that
is difficult to troubleshoot and has no advantages over a simple 3-way.
