Be careful with very small company 401(k) plans. It's very likely your company did not pay attention to expense ratios within the 401(k) plan. Most of the people complaining about really bad choices tend to be smaller companies with newer plans.
I'd highly recommend taking some of the fund names in your plan, and doing a Google search where you append "Morningstar" to the search. If they list "Voya Growth", you search for "Voya Growth Morningstar" and view morningstar's data about it. You should see an "expense ratio" or "fee" near the upper right side. If it's 0.25% or lower, it's good. If it's near 1.00%, not good at all. (Voya and American Funds tend to have bad expense ratios)
If you don't invest, or only need to invest a few thousand, an IRA might be a better option. You can choose where you open an IRA, and pick your investments. Vanguard, Fidelity and Schwab are all good choices for that - but again, pay attention to expense ratios. That's how much of your money the fund consumes every year, so it's important.
