My setup meets your requirements. As a server, I use a QNAP NAS, which comes with apps for a one-click install of several music/media server packages. I run Minimserver for home and Plex server for remote access. In general, this is a much lighter install than Roon, and involves no Apple products. QNAP has its own media server, which I've never tried. You could also try Bubble UPnp Server, which should work well with the control point I'm recommending. I've never tried that either.
From an Android Tablet you can run Bubble UPnP as your control point, it will see Minimserver and Plex, and it will broadcast to all DLNA renderers and Chromecast (perhaps more, I'm not sure).

If you have WAV files, you may need to also enable Minimstreamer for format conversion to certain renderers/endpoints- I'm not sure whether all your renderers will accept them. My library is about 1100 FLAC albums and 100 or so DSD (.dsf), so only the latter ever require transcoding. Plex, I believe, will also let you set some transcoding options.
If your collection is well tagged, and/or contains classical music, Minimserver is an excellent product. If it isn't, Plex, like Roon, will supply a lot of the metadata on its own. And if you have video, or require remote access, Plex is far superior. Any of these servers should show up in proprietary player apps (like Cambridge Audio, Muzo, Krell, etc.)
