Would it be of any benefit to convert my long term swing/investment account into a Roth IRA?

So basically I have one brokerage account that I primarily (probably 80% of my portfolio) pick indexes and certain mega caps to buy and hold indefinitely, but the other 20% I either keep in cash or experiment with other more volatile, but still higher cap, growth companies that I may or may not hold long term if they continue to meet my investment criteria. My question with this is, would there be any benefit to converting this sort of account into an IRA for tax purposes, considering I buy and hold most of the assets for the long run? Or would those benefits not be worth it if I still actively manage and buy and sell an asset or two every once in a while. Appreciate any advice
