What is your marginal income tax bracket?
If you are in the 25% tax bracket, then any gains in this VA will be taxed at 25% when you withdraw much like an IRA. But it is worse than an IRA since you paid taxes on the money before you put it in the VA.
OTOH, if you had invested tax-efficiently in a taxable account with index funds, you could pay as little as 0% tax on the gains or at most about 15% tax on the gains.
The math should be compelling: Which tax rate on gains is better? 0%, 15%, or 25%?
Investing tax efficiently in a taxable account also gets you tax-deferral. Unrealized capital gains are not taxed. The taxes are deferred until you realize the gains.
Or investing in a Roth IRA account would be better, too.
Some annuities make sense, but you haven't described any reason whatsoever why this one would make sense. If you were extremely wealthy with high income and had made all possible contributions to IRAs, 401(k)s, etc, and wanted to have more fixed income assets and would invest for 30 years, then a VA might make sense, but even then a low-cost muni-bond fund would probably be better.

With no withdrawal penalty, it may be time to get out of the VA at Fidelity and do something else with the money. However, there is no rush. Don't jump out of one thing into a worse thing.
