Wealthsimple vs other brokerages for a larger long-term portfolio in Canada?

Wealthsimple vs other brokerages for a larger long-term portfolio in Canada? I’m expecting to come into a fairly substantial amount of money and plan to invest a portion of it long term. I’m still fairly new to investing and currently looking at Wealthsimple. For those who have used Wealthsimple or other Canadian brokerages, what would you recommend for a larger portfolio? I’m particularly interested in fees, CAD/USD conversion costs, TFSA/RRSP support, customer service, and anything you wish you knew before choosing a platform. Thanks in advance.
