If you can do simple math and have some time on your side, I would argue you could do just fine. I will give you some encouragement. Here is a Fidelity Fund I found I am invested in via one of the variable life insurance plans.
It has never beat the S&P 500!
The allocation could have been picked by an elementary school student. Top 10 holdings: Microsoft, Meta, Google, Apple, Amazon, Eli Lilly, Berkshire, United Health, Costco
As you can see above, it has two very very very smart humans who are paid very well to manage this fund that has never out performed the S&P500! EVER!!!
I have re-allocated majority of all my longer term account to where I want to invest this money. If the account only offers 10 options all with same basket of asset classes and holdings, I have moved those accounts away from that provider. I recommend you get your house in order as well!
And please revisit two of my older posts:

Look at the relative performance of Nasdaq/SPX/large-cap vs small-cap, vs commodities, vs foreign stocks.
Lots of under covered areas away from indexes and funds. I can't even find funds, in the U.S. at least, the cover overlooked areas because nobody wants them. The coal ETF KOL shuttered at the end of 2020 right as the bull market was taking off. Or they cover the market, like China dividend funds, but yield 1/2 to 1/3 of what can be obtained by going "dumb long" the biggest, higher yielding companies. I found many 10x stocks in the list of ADRs back in 2000, most were emerging markets like Brazil, Russia, China, etc. After two decades of globalization, many markets including Hong Kong, Indonesia, China, Malaysia etc. have plenty of opportunities for those willing to look.
The tax planning stuff is pretty important tho. As long as you bring in someone to optimize that you’re solid.
