Best Tablet choice for my scenario with HA

Hi everyone, I’d like some help picking my first tablet, which will be used as a Home Assistant dashboard. It won’t be wall mounted, it will sit on my shelf almost facing me. The idea is to leave it almost like a Windows desktop mixed with a dashboard, meaning I want to have a photo slideshow running on one side while the other side has, for example, a card with one or two cameras. I’d also like to be able to add some animated GIFs, see notifications from my automations, calendar cards, and so on, or whenever I want, just a nice wallpaper in the background with a few notifications, etc.

I’m researching Fully Kiosk Browser for this. The thing is, I don’t know how much of the tablet’s processing power this will actually use. Anyway, the idea is to have a dashboard with several options, running super smoothly.

I was initially thinking about buying the Redmi Pad 2 with 8GB for this, but I’m not sure if I’ll run into processing issues for the things I want to do. Because of that, I was also considering the Xiaomi Pad 7 with 8GB, which would have a lot more processing power, but I don’t know if I’d be spending money unnecessarily.

I’d appreciate your opinions, please.

Not expert on the SW side but for the HW I’m researching for a similar setup and I’m inclined to buy a used Lenovo M10 tab with his dock, It will give a “professional” look at the thing…
