Is VOO a good index fund to invest in as a beginner?

Hi, I’m currently 19 years old and have a decent amount in my savings account but it’s not doing anything besides sitting there at 0.5%. So I’m thinking of taking a decent chunk out of that and putting that into VOO or another S&P 500 index fund. Also is it smart to do dollar cost average by doing recurring investments instead of just dumping all the money in at one time (for example $1000 every 2 months) until I reach the amount I was initially planning on investing? I just opened an account with Vanguard to hopefully get started on this.
