Fujifilm XT3 might be a very good option if you able to extend your budget. Or XT2. Much better than X-T100 and IMO have good image quality and best SOOC image. From your list I think A6500 should have the best image quality among them but A6500 is more for video production. Fujifilm XT3 is better choice if you shoot photos more than recording video.

Most of the Fuji prime don’t have stabilisation except 80mm macro but some Zoom like 18-55 and 10-24 have stabilisation. I mostly used Fuji prime myself and is very statisifed with the image produced. The SOOC jpeg images is just so nice! Stabilisation is a nice feature to have but does not make a big difference for photo taking, but makes a difference in video recording.

If you getting a camera for photo shooting, I think stabilisation should not be the main factor of decision. It’s more for video production. That’s why I don’t recommend X-H1 over X-T3 although H1 have IBIS but the dynamic range of XT3 just overthrow the benefit of having IBIS. If IBIS is your main concern then I suppose A6500 will be a good choice. But it would be nice if you could state your usage of the camera too, it helps in recommendation of the right camera too.

Handheld Still subject under low light, I think you might benefit from having an IBIS in that case.
Having a large arperture prime with out stabilisation means you can compensate the lowlight and higher shutter speed with the large arperture, but zoom with stabilisation means you have to compensate the lowlight and the smaller arperture with low shutter speed, which is not really practical unless your subject is completely still. I shoot family and street more, so too low shutter speed will be some problem for me.

Been Eyeing on A7M3, but the Fuji colour and jpeg is just too hard to give up. That good jpeg processing just saves me a lot of time.
Currently using Fujifilm XT2. I often does the same routine as you too! Import jpeg straight and edit in phone.

I agree that sharp image is much more important than micro details. That video do changed my perspective on IBIS. However, it is quite hard to get a sharp image with 56/1.2 @ 1/30 or lower shutter without stabilization. Its just the matter of priority for TS.
