I think you'd enjoy the work of Bernardo Kastrup, who is a proponent of idealism, while also arguing against panpsychism, for basically the reasons you just stated - ie, there is a reality made of parts, and those parts are x, where x is 'matter', 'mind', 'consciousness', 'electromagnetism' and so on. But the trouble then is that you can only describe the constituent parts in terms of those parts. For example, subatomic particles have properties like spin and charge, but that's the only way you can describe them - in relation to one another - without having to go a level 'deeper' if it were possible to describe them in further parts (which would only be describable in terms of those parts, and so on).
