Starlink dishes need an open unobstructed view of the sky to communicate with the satellites. You'd need the dish to be outside and then be in range of the wifi from the dish's router (or other routers or mesh system you set up).
IMHO Starlink is best when living or boondocking in remote area without other options and with enough open sky view to get a decent connection. I have a Starlink dish on my van to get internet access when 5G coverage is not available.
The new Starlink Mini dish might be of interest - a small dish, power-able by 12-48V DC or USB-C PD. In the US it is $600, then $30 a month but only 50GB per month before extra charges.
FMCA TechConnect+ has some plans including an unlimited but speed capped AT&T plan for around $60 a month.
