Boutique Firm vs Big Name Firms? Where to go? Or eXp Realty?

I recently obtained my Broker’s License in Colorado for the first time. I’m looking to make a transition from tech (currently a Software Engineer at a big Real Estate tech company) to Commercial Brokerage. I’d appreciate any suggestions on which or what kind of firms to apply with.

I know CRE is demanding and may not see a paycheck for months or even beyond a year and am prepared to enter a turbulent market. Thus, I’m valuing effective training, mentorship, and key skills that I can pick up from those already successful in the business. Would the big names like CBRE, C&W, Marcus, etc be the better choice? Or would local boutiques offer better alternatives with specialized training?

Would appreciate any insights you all have. Thank you in advance!
