TL; DR version
To get close to your stated wants,
(1) get a compact Sony RX100 Mk. VII with an f/2.8-4.5 lens, and accept a long end equivalent to 196mm, or
(2) get a Sony RX10 Mk. IV with an f/2.4-4 lens and a long end of 600mm, and accept that it's not compact, or
(3) accept something even further from your stated preference.

Thanks for the camera size comparisons.
You're welcome.
To clarify: I understand the limitations of cameras. I'm looking for suggestions of models closest to my wish list. Then I can "adjust" my wish list to reality. When i said I thought I was done with changeable lenses, I meant when I picked my current ZS200.
The ZS200 is limiting me to too slow of shutter speeds because of f3.3-6.4
For sports I'd like to shoot 1/1000-1/2000 sec.
For the maxed out zoom(360mm equiv), most lighting, I can only get about 1/60 sec, iso 640. For min. zoom, 1/250 sec. iso200.
Shoot either raw or raw + JPEG and process with DxO PhotoLab Elite, and I think you can go far higher than ISO 640 with good quality.
So, is a NON changeable lens camera available with an equiv zoom of about 24-300mm with aperture of about f2-f4 available? If not I'll have to go to multiple lenses. I was hoping that the 1" sensor format would have something only to keep the actual size smaller.
There aren't many 1" sensor options with long-ish ( > 150mm equivalent) lenses that are theoretically (availability is tight) sold new today:
* Sony RX10 Mk. IV: 24-600mm-equivalent f/2.4-4 lens, not compact; or
* Sony RX100 Mk. VII: 25-196mm-equivalent f/2.8-4.5 lens, fairly compact.
As previously mentioned, there's the apparently-discontinued:
* Panasonic FZ 1000 Mk. II (and apparently-similar Leica V-Lux 5): 25-398-equivalent f/2.8-4 lens, not compact.
And then of course there are older, longer-ago discontinued models, including another Panasonic ZS200 (or its near-twin, the Leica C-Lux).
Last but not least, you mention sports, and AFAIK
only the Sony models have autofocus systems even moderately appropriate for sports. They both have PDAF. I don't think and of the Panasonic / Leica models do.
