Schwab are also a good choice (as Another Reader already mentioned): they have some very competitive Funds/ETF's that trade commission free.
+1.
I have used Schwab and find them very good. They would be my first choice. My second would be Fidelity.
I'm surprised you have so many choices. worked for financial companies for 20 years until I FIRE'ed in 2018 and I would only get one or two choices (e.g when I moved to Merrill Lynch, had to use the Merrill brokerage which I hated)
Schwab have a nice deal where if you transfer in $100k in assets, you can get 200 free trades for 2 years. (You need to register for the deal before sending the transfer.)
Every time I switched a job, I was forced to move my funds to a new brokerage. I would find out what cash awards were available to move funds. E.g. Move $500k and the brokerage would add $500 to your account. I would find out awards given by all companies, even those not in the list. Then I would ask the brokerage to match it. I made out like a bandit with several moves ;-)
