New to traditional investing, which online brokerage would you recommend for UTs, stock picks & REITs?

Have been a crypto investor for a few years and purely crypto, kinda dumb not to diversify and I am looking into expanding my portfolio as well.

I just signed up for DBS Vickers, I am not sure if that’s the best choice right now but what do you guys think? I don’t mind navigating shitty UI, I am looking at something that is cheapest and have the following:

• Wide range of UTs & ETFs
• Access to US, SG, HK markets
• REITs
• Options

Not looking at using robo-advisors, already on stashaway.
