If you are looking for "simple" and "inexpensive" then look at Samsung Smarthings hub.
If you are looking for Voice, then Alexa and Google Home supported products. But, these are cloud services which you say you don't want (I get that). But they work good and are super inexpensive. You just give up your data.
HAL is an automation system that does quality VR for command / control and it is processed locally. But the UI is not up to snuff compared to some other products.
Touchscreen: You can glue a tablet / phone to the wall and call that a wall mounted touchscreen. And most all automation systems support iPhone / Android devices with an "App". If that's what level of quality you are looking to pay for, there are lots of mounts that can make the install easier.
If you are then talking about media control, the pack gets smaller.
myServer does everything you are asking for, but it will be more expensive than Smarthings (as one example) and will require someone to configure it to your specifics. We can do that for you for a fee. You can then tweek and support it ongoing...or pay us to do that for you. We have a full PLEX (and Kodi) integration which only a few really do well. Completely customizable user interface (that requires custom configuration if you want to modify it from the samples provided).
If you truly want all the elements you are asking for, there is no single product that does all exactly how you are asking. You are asking for a custom system without the custom system cost or complexity. You will have to compromise on what's most important. I think the largest issue is cost vs. cloud. The two don't go together. Non cloud systems are more expensive (and much better). Consumer electronics level systems (smarthings) are loss leaders to get your data and habits and to pull you into their ecosystem. That's why they are inexpensive. There are three levels of cost: Consumer electronics level (smarthings), software centric systems (myServer, CQC, Homeseer) and there is the expensive stuff (Crestron, Control4, Savant) that are dealer only installed systems. From your description, you are not remotely close to the expensive stuff. You just have to determine what your real budget is to decide on consumer or software based. All of your description points you to software based, with the possible exception of cost and you don't want to program it. Note: EVERY system requires configuration by someone.
With regards to wiring needs: First plan out what you are trying to achieve phase 1 and later...sounds like you are doing this now. Phase 2 is pick an automation system. Phase 3 is pick devices (including software devices like PLEX). Phase 4 is plan your wiring. Phase 5 is wire it before insulation and drywall. Phase 6 is install equipment. Phase 7 is Program it. Phase 8 is enjoy the system. You are ahead of the plan. There are MANY posts on generic wiring tidbits on this and many other forums. Without the specifics learned in Phases 1 - 3, you will have to overwire lots of stuff because you really don't know what you will need. But you only get one shot at doing wiring efficiently.
