Planning on bolstering my portfolio against taxes. I'm relatively inexperienced when it comes to the market, so I would like some advice.

I currently have a taxable account with 15k in VTI and 7k in FBGRX. I was doing some research and saw that FBGRX has a high tax rate, so I want to switch it out with maybe another etf, possibly with international coverage. Any advice on how I can maximize this? I'm 24 and want this to grow for 30-35 years at least maybe more. I'm starting a new job next week, so I'll be contributing around 1500 a month.
