What to do with LIRA account?

I commuted my pension from work in March 2021, and got a lump sum payout of $256,991. I had to put it into a LIRA account and went with CIBC, since they were my primary banking centre. I was just recently talking with a fellow worker and they self manage their LIRA account. I decided to finally look deeper into my account and after totalling all the monthly management fees, I’ve given CIBC $19737 since March 2021 to manage my money. I noticed in this time that they only have changed my account holdings once. Also in this time my account has now increased in value by $119828. The fees have now increased to just over $500 a month and will continue to increase as my account goes up. So should I try and self manage my LIRA account and save $500 a month. Any suggestions where to put my money into? I do have some knowledge of investing so this does seem possible to me. Also Iam 47 so I this money will be locked away for quite some time still.
