FLMI
Franklin Dynamic Municipal Bond ETF
stock NYSE ETF

State income taxes don't apply? Then be sure to include munis that avoid federal taxes.
Control costs now. If you're trying to amass wealth on top on the guaranteed 80K/month, more savings early in the timeframe is a real advantage. Likewise, keep after it.
If the person is willing/able to work at it some, direct investment into property might be an option to do some tax things. REIT likely wouldn't have the tax advantages but could provide the diversification.
One possible allocation could look like this: 25% SGOV or similar, 25% FLMI or similar, 15% international index fund, 35% broad US index such as VOO/VTI/SPYM. If 50% stocks is more than your comfort, dial it back into TIPS and/or SGOV (RETI and/or property fits here too).
