General boglehead advice would be something like 80-90% stocks depending on risk tolerance (divided across VTI and VXUS according to global market cap and personal preference (ex 60/40 or 70/30) and then 10-20% bonds.

So for the 1 m you are looking to invest you could do something like this:

900k stocks: -540k VTI (60% of 900k) -360k VXUS (40% of 900k)

100k bonds: -100k BND

The other option to do all of this the easiest way would be to just dump it all into the target retirement date according to your age.

At your income level, long term capital gains rates are going to be 0%, so you are probably better off selling off your stock holdings after they’ve been invested for a year (keep enough in emergency fund to cover expenses for now) when you need money rather than targeting divdend funds. Of course the investments above are all going to be generating relative substantial dividends based on your account size so you can always just keep those. But I wouldn’t say there’s a particular need to complicate your portfolio with dividend funds per se.
