Best Internet Plan for WFH & Tech Heavy-ish Home??

I am trying to choose an internet plan and don't know what we need mbps-wise. This will be my first time owning a home & paying for my own internet service, and Xfinity/Comcast is really the only provider in my area. Details about my situation:

- I work from home via company laptop and 2 monitors. HEAVY data usage, i.e. Zoom, graphics editing, coding, etc. Work VPN/network bounces from FL to a server in CO to me in WA, then back again for most work activity. So my work laptop is already slowed down by this, hence why I have it connected directly to ethernet. Will likely do the same in my new house. 

- personal Victus HP laptop used for life stuff and sometimes gaming.

- printer connected via wifi, used semi-regularly

- 2 iPhones used regularly. I use mine quite heavily.

- 1 iPad, used by other person quite heavily.

- 3 TVs: 1 per bedroom, 1 in living room. All used daily, mainly in evenings. 

- Nest AC/Heat system - I'm assuming this uses wifi? 

I'm thinking of choosing either the 800mbps "Superfast" plan for $75/mo, or the 1000mbps "Gigabit" plan for $85/mo. I will likely buy my own modem and router. 

Any advice?
