16K to invest. 401K and Roth IRA already taken care of. What would you buy?

Well it’s not really a 401k. It’s a profit sharing account my employer contributes 20% of my yearly earnings into.

401K allocations:
VTSAX 80%
VTIAX 20%

Roth IRA:
FSKAX 80%
FTIHX 20%

For this 16K, I was thinking:

VTI 70%
VXUS 30%

Or

AAPL 25%
MSFT 25%
AMD 25%
NVDA 25%

Or

AMZN 100% (kinda joking but maybe not)

The 16K would go into a regular taxable brokerage account.

any suggestions are much appreciated.

Thanks for reading.
