Hi. We use the monitor for the home office and I can't give an opinion on the subject or a comparison with other monitors. But it is definitely not a photo monitor, even though we use it ourselves to edit photos with Lightroom. Sorry!

Mac Mini works well

Yes, the monitor has built-in speakers. The sound is OK for the small size. Please do not expect too much. I can recommend this monitor without any ifs and buts.

It's an IPS panel, it's what you need, but it doesn't have Adobe RGB colourimetry, it's only sRGB. So I would say that it depends on your use, if your photos are meant for screens, it will be fine, if they are meant for printing it is better to go for an Adobe RGB screen. The only "affordable" 27" 4k Adobe RGB screen is the BenQ SW271. Have a nice day.
