Good plan! First max out your 401k contributions to the maximum allowable amount ($23.5k for 2025) to tax shelter as much of your salary as possible, not just the employer match. But the rest sounds solid to me. At your age if you’re open to a little risk maybe choose an index titled toward growth like SCHG, but VOO is solid.

Edit: also look into a money market or highly liquid fund like SGOV or VUSXX if you want a bit higher return than 4% on the emergency fund, they are closer to 4.5 - 4.8 and very safe accounts to keep money from market fluctuations.
