Answer 1

Solution:

• This solution uses google-apps-script. This does not need array formulas, but uses autofill. For the solution to work, you should not use array formula, but plain formula.
• Get the active range, which will represent the current range inserted onChange or onFormSubmit.
• offset the range to the right to get the calculated columns and expand the range to all of calculated columns on the right.
• Use range.autoFillToNeighbor to fill all the calculated regions of the range.

Sample script:

/**
 * @param {GoogleAppsScript.Events.SheetsOnChange|GoogleAppsScript.Events.SheetsOnFormSubmit} e
 */
const onFormSubmitORonChange = e => {
  const rg = SpreadsheetApp.getActiveRange(),
    wd = rg.getWidth(),
    sh = rg.getSheet(),
    lc = sh.getLastColumn(),
    numRows = Math.max(
      rg
        .offset(0, wd, 1, 1)
        .getNextDataCell(SpreadsheetApp.Direction.UP)
        .getRow() - 1,
      1
    ),
    numCols = lc - wd;
  sh.getRange(2, wd + 1, numRows, numCols).autoFillToNeighbor(
    SpreadsheetApp.AutoFillSeries.DEFAULT_SERIES
  );
};
