I did go with a Pi option for the main TV, for the secondary one picked a discounted Firestick + wolflauncher using this tutorial https://troypoint.com/wolf-launcher/
The Pi does a lot more 💪 besides media playback for the TV while it’s on , but the Firestick was $19.99 at some sale 🤷
Or use any of these
