Roth IRA: Target Retirement Fund vs Total Stock Indexes

[EliteZags]

I have my Roth IRA approaching 6 figures in Vanguard Target Retirement 2050 (hope to FIRE at least 10-15 years sooner) mainly since it seemed to make sense when I opened it as a hands off fund that takes care of itself.

Now analyzing this fund more closely https://investor.vanguard.com/mutual-funds/profile/VFIFX

it's really mainly just 2 funds I already hold in my taxable:
   Vanguard Total Stock Market Index Fund Investor Shares 54.40% 
   Vanguard Total International Stock Index Fund Investor Shares 35.60% 
   Vanguard Total Bond Market II Index Fund† 7.00% 
   Vanguard Total International Bond Index Fund Investor Shares 3.00% 
   

I don't really have a set allocation in mind, but the rest of my portfolio is <5% International Index, and not holding Bonds anywhere else currently

Trying to decide if it's worth moving the Roth funds out of the Target and just putting them into Admiral Stock/Intl Indexes, mainly since the Target fund has 0.15% expense ratio (0.4%/0.11% for the Admirals), since exchanging funds within Roth can be done freely without creating any taxable events right

I don't plan to buy a home/vehicle or need major funds anytime soon, just currently pumping everything saved into VTSAX/VIGAX
hoping to hit 7 figure NW within 5 years and FI within 10-15

You'll know when you find your hindsight glasses.

Staying with the target fund or moving as you suggest are both defensible choices.

You can do even better if you use ETFs (Exchange Traded Funds: like a mutual fund, but it has it's own stock symbol in the stock market).

You could buy Vanguard Total Stock Market ETF with a 0.03% expense ratio, and
buy vanguard Vanguard Total International Stock ETF (VXUS) with a 0.09% expense ratio.

My worry here is you might be penny wise (0.15% vs 0.11%) and pound foolish (5% international).  Vanguard has studied diversification, and they picked a 40% allocation.  If they get it wrong, clients who invested billions at Vanguard will sue them.  They need to get it right, so they might know something you don't.

but they don't get sued for lower positive gains/returns than the total stock index, as historical and expected
It's more about risk mitigation
