~22,000 in taxable to help fund ROTH and HSA over the next few years. What should I invest it in?

I have ~$22,000 in a taxable investment account I am planning to sell off at the end of each year and transfer to VT in my Roth/HSA accounts. I was told to hold it in VGSH. Is this a good strategy from a Bogleheads perspective, or what do you recommend instead? Thanks and my apologies for being a novice. I tried searching this question and couldn't find a certain/definitive answer.
