Sealed monitors down to 35hz....not many of those due to laws of physics. More realistic is 40/50hz + allow for room gain of 3-6db.
Monitors with downward facing ports on a stand? Not a good idea. They also, um, don’t exist.
For everything else you want, wholeheartedly recommend ATC SCM7/11/12/19/20s. Don’t know your amp, but these ATCs match your speaker requirements.
For an easier load/drive and the classic British monitor thing, I’d look at Graham Audio (which I prefer to Harbeth).
I wouldn’t rule out floorstanders. They’ll take up the same space as a monitor on a stand!
