I'm looking for a standard zoom lens for the z50ii

I’m currently shooting birds with a Z50II and the 180-600mm, but I’ve recently realized I need a new standard zoom lens. My main subjects are daytime outdoor snapshots, plus occasional nightscapes and astrophotography. I generally prefer buying used. My current candidates are:

• Z 16-50mm f/3.5-6.3: Lightweight, compact, affordable, and looks decent when retracted. However, it's a 'slow' lens, and I'm worried about vignetting and poor flare resistance.
• Z 18-140mm: Brighter than the 16-50mm at equivalent focal lengths, offers higher magnification, and has more reach. But it’s still relatively slow, shares the same concerns regarding vignetting/flare, and I’m not a fan of its 'cylindrical' aesthetics.
• Z 24-70mm f/4 S: Constant aperture, high build quality, and looks great. It has strong flare resistance and minimal vignetting. However, the wide end starts at 36mm (equivalent), which makes me nervous for those 'just in case' wide shots, and it lacks Vibration Reduction (VR).

Which one do you recommend? Also, are there any other lenses you would suggest?
