What exactly do you find messy and don’t like about VT? Dividends are a natural part of any equity investment. Even with accumulating funds you’ll have them and will be forced to pay taxes on them. There’s no way to avoid them.
If you’re allergic to any sort of dividends, you could buy gold, I guess. That one never pay any divs. Only has costs.
If you’re worried about bookkeeping, then just open a secondary account for this side portfolio. Either real (IBKR allows multiple accounts, all can be linked to same login and account holder; but there could be extra fees) or paper trading account just for keeping track of pure loss/profit.
Lastly, why the hell does your daughter even need a separate portfolio? How old is she? If under 18, her wealth is your wealth for most practical purposes, so focus on maximizing your wealth and don’t drag yourself into pointless accounting gyrations.
