What’s the best strategy as a 30 year old?

Just curious what would you all say I should prioritize to invest in for my taxable account that I just opened? for some context I've maxed my roth ira for 3 years now and is about 80% s&p 20% international- roth ira account is with fidelity

My taxable account is with fidelity as well, should I go some VTI, VOO, a combination of those two and more? I know they're some possible overlapping at times but wanted to hear what you all thought, pros/cons etc. I appreciate the advice
