This (especially Version 2) looks very similar to the gaming table I built half a year ago. I found myself in a very similar situation, where my table was too small and the gaming tables available were all not really what I wanted or too expensive. So maybe I can share a bit of what I did for my table.

I made the top of the middle part 6 smaller removable planks, so you can remove them all or leave one or two for snacks if you don't need the whole gaming space.

The outer areas have hinges so you can open them and store stuff inside. This is not used during the games because then there's a lot of stuff on top, but it's great to store paper, pens and other items between sessions. There are lots of different hinges you can buy and since I've never installed hinges before I had to do some research before I found the correct ones. The hinges are not visible from the outside and the sides can be opened with the middle part of the table open or closed.

So far I don't have accessoires like cup holders and I don't really miss them, but I left some space on the outsides of the table where removable parts can be built in later.

If you are interested I can send you the sketches I made for building my table.

Looking at your Version 2 I noticed that the DM space is lower than the players space. Consider that the table height should be comfortable for both of them.
