In VSCode with the extension vscode-neovim installed:

How to set up the keybindings so that, for example, ctrl+u moves the screen a half-page up, and then centers it vertically?
Vice-versa for down and full-page up/down.

I tried this in my keybindings.json:

[
  // disable the actual ctrl-u
  {
    "key": "ctrl+u",
    "command": "-vscode-neovim.ctrl-u",
    "when": "editorTextFocus && neovim.ctrlKeysNormal && neovim.init && neovim.mode != 'insert'"
  },

  // send the ctrl-u + z. for centering
  {
    "key": "ctrl+u",
    "command": "vscode-neovim.send",
    "when": "editorTextFocus && neovim.ctrlKeysNormal && neovim.init && neovim.mode != 'insert'",
    "args":  "<C-u>z."
  },
]

But after these changes, half-page up and down commands now jump 100 lines (instead of 20 like before).

Problem

The problem seems to be related to the commented-out code from the vscode-scrolling.vim file:

" Disabled due to scroll problems (the ext binds them directly)
" nnoremap <silent> <expr> <C-d> VSCodeExtensionCall('scroll', 'halfPage', 'down')
" xnoremap <silent> <expr> <C-d> VSCodeExtensionCall('scroll', 'halfPage', 'down')
" nnoremap <silent> <expr> <C-u> VSCodeExtensionCall('scroll', 'halfPage', 'up')
" xnoremap <silent> <expr> <C-u> VSCodeExtensionCall('scroll', 'halfPage', 'up')

[...] (same for full page and line)

(Edit)

Workaround

I found a workaround for this problem, this involves setting the keymaps to execute both commands as a sequence:

Install the multi-command extension.
Go to your Keyboard Shortcuts JSON.
Set new keybindings for Ctrl+d and Ctrl+u with the following:

{
  "key": "ctrl+d",
    "command": "extension.multiCommand.execute",
    "args": {
      "sequence": [
      {
        "command": "vscode-neovim.send",
        "args": "<C-d>"
      },
      {
        "command": "vscode-neovim.send",
        "args": "zz"
      }
      ]
    },
    "when": "editorTextFocus && neovim.ctrlKeysNormal && neovim.init && neovim.mode != 'insert'"
},
{
  "key": "ctrl+u",
  "command": "extension.multiCommand.execute",
  "args": {
    "sequence": [
    {
      "command": "vscode-neovim.send",
      "args": "<C-u>"
    },
    {
      "command": "vscode-neovim.send",
      "args": "zz"
    }
    ]
  },
  "when": "editorTextFocus && neovim.ctrlKeysNormal && neovim.init && neovim.mode != 'insert'"
}
