21 Year Old Getting Into Investing

Looking to get into investing after paying off my credit card debt soon, I was going to go all in on XEQT, but being young I think I rather go for growth unless otherwise somehow persuaded, I have a lot of patience as I believe whatever I chose will pay off in the end so looking at 15-20 years, I have been recommended SCHG but many have suggested other growth ETF’s such as IGM, IVV, IWY. I am curious what the opinions are of those few ETF’s and what you would chose to someone in my position of an indecisive 21 year old Canadian that’s looking to put money away to invest.
