Please help-which colorspace to select for applications and camera?

Would like to have some advice as to how I can best 'set' the various colorspaces.
1. Monitor HP Dreamcolor Z27X
currently set to: AdobeRGB
other options: sRGB D50, sRGB D65 and some other somewhat unfamiliar profiles to me
(BT.709, BT.2020 DCI P3)

2. Camera: Sony RX100 M3
currently set to: AdobeRGB
other option: sRGB (no D50/D65)

3. ACDSee Pro v9
Input Profile: AdobeRGB

4. Adobe Photoshop CS6
default color settings
Monitor Color
RGB: Monitor RGB - HP Z27x AdobeRGB ICC Profile

5. for quick viewing images I use XnViewMP and do not have any color space settings there.

I'd like to have the same view everywhere, i.e. if I apply some changes in ACDSee and save the image and re-open it in Photoshop or XnView, it should look the same.

No matter with what application I open it, the colors, contrast, etc. should look
the same.

Attached some screenshots of settings.

I am far from being an expert...
Neither am I doing any complicated editing etc.

What are then the recommended settings for all the above stuff.

e.g.
Should I set the camera to sRGB
and all applications to use HP Z27x sRGB D65 ICC Profile.icm ??

Thanks
