Thanks for the double post. Lol
Here's the meme that the player sent that started the idea:

So I might eventually be making an interprative dancer (probably part bard college of movement, part shadowdancer).
Now for the beholder PC, I think what's missing are some simple ways to manipulate & hold/carry things.
I'll probably say it can manipulate doorknobs/levers, buttons, and other simple mechanisms with its mouth & tongue combo, taking twice as much time as normal (2 actions), with disadvantage when rolling, and preventing speech.
It can pick-up and carry 1 item in its mouth (again no speech) but not use as a tool or weapon.
It could probably have a specialized backpack to carry items.
It could wiggle eyestalks for somatic components and use a stalk band or a pendant of some sort for an arcane focus.
