Staying in WPB for around 6 months. Any Wireless/Internet plans advice?

Hello, I will be renting a new apartment and will be staying there for around 6 months. Since I'm coming from another nation, I need a new phone/internet plan. I will be only staying in West Palm Beach.

I found out that there are a lot of options; Verizon, AT&T, T-Mobile, Google Fiber/Fi, Xfinity...etc.

For the wireless phone plan, I prefer 5G unlimited, and I want the one that provides the best speed/stability in my place.

With the internet plan, I would like fiber with 1Gbps or higher speed. It should also be stable.

Which plan do you think I should go for?
