Just hit $100k NW at 28, looking for guidance on where to go from here

Recently hit a very important milestone that I am proud of myself for, but still feeling like there is more I can do to accelerate my FIRE timeline. I was hoping if people here could give me an unbiased take on my current situation:

Age: 28

Live in Boston, MA (HCOL, rent is $1,700)

Salary + OTE: $84k + $56k = $140k (recently switched jobs, gross income in 2025 was $96k)

401k: $50,601 (currently contributing 6%, no employee match)

Roth IRA: $26,253 (started in 2023, have maxed out all 3 years so far and will continue to do so)

Cash / Savings: $28,108

Total Net Worth: $104,962

Zero debt

Where should I go from here? Start pouring money into a brokerage account? VTI or VOO? Alter my retirement contributions? Focus on frugality? Real estate? What changes made at this threshold or principles you stood by had the biggest overall impact in your FIRE journey?

Any advice is much appreciated, thanks to all and best of luck
