Passive bi-amped is no more or less inherently detailed than active bi-amped.
Maybe. My research into pro-designed-but-not-hugely-costly powered monitors is that they often (yeah, not always) have in-built DSP that is factory 'firmwared' to better drive the particular drivers and enclosure they are bolted
to. The result can be a tightly controlled system of amps and speakers that were intended and designed to work together. This bypasses many of the troublesome issues of trying to pick, choose, and match amps and speakers that might not play well together.
In my use of desktop
monitors, I rarely change any performance parameter other than volume.
I don't need lots of input selectors, tone controls, or cables and wires. And a convenience feature I like is having a headphone jack that cuts off the speakers when I just want headphones
for a chore. If you do look at powered monitors, you may find that headphone jacks are scarce.
Also, you may wish to have any analog inputs of powered monitors be balanced for noise immunity and future compatibility. Me? I'd look for a powered speaker digital input that matches the digital output of my computer/DAW.
Try to keep in mind that the major difference between monitors and HiFi loudspeakers is that monitors are a tool
for use in a workflow situation. They are not audiophile toys for the music-playing cognoscenti.
