When you say portraits, what are you hoping for?
If the X100F appeals but is too expensive the Fuji X70 might appeal. But the lens is a little wider and not as fast. It still has the apsc xtrans sensor though, which is a good thing. It will produce great IQ but obviously the fixed lens (28mm eq) requires a different approach.
If you do like a fixed 28mm lens, the Ricoh Gr is a great camera.
Pana LX100 is also a great little camera. Good fun to use, lots of external controls and a decent size sensor (although it doesnt use all of it in certain aspect ratios). Its now a runout model and top value imo. Has an EVF too and the lens is good though not a huge zoom range.
The Rx100 range is good in IQ but Sony ergo’s can be a bit hit and miss for some people. Mkiii and beyond have a nifty little popup EVF. Smaller sensor but probably just as good for IQ most of the time.
Keep in mind that the smaller the sensor, the less ability to throw backgrounds out of focus. Hence asking what you want from portraits.
The super zooms are obviously far more versatile but generally slower and will stretch the iso capabilities of the sensor.
