Anyone in Seattle with 5G home internet?

Curious about the $35 plan being advertised. We are currently paying $200/month for Xfinity WiFi and cable and looking to cut the cable. Currently says this is my internet

Download speeds: up to 600 Mbps Upload speeds: up to 150 Mbps

About us: live in the city, I work from home (so need decent connection for video calls). 2 tv’s for streaming platforms (only watch one at a time) and 2 cell phones we usually stay connected to WiFi, one kindle to stream (plus the aforementioned laptop I work on and use for 2-3 hours of video calls a day). No actual desktop computers or video game consoles. I honestly don’t know about upload/download speeds and how that translates to actual usage. Is what we have overkill for our usage? Would love any thoughts or can answer additional questions to help figure out if this will work for us.
