Is it a tablet I'm wanting (and if so, which one)?

I do a bit of coaching and I'd like to video the rider so we can play the footage back and see where improvements can be made.

I'm also thinking it might be handy to get setup for a simple Zwift-type interactive session on the turbo - but I'm not looking for stunning footage.

I'm tight so would be wanting something with a decent amount of memory and storage as it would be needing to be used for a few years - footage isn't really intending on being kept, but I'm thinking it might have quite a few videos from a days session.

Not needing data but wifi would be good as I could hotspot it to my phone if needed. I think I'd be needing Bluetooth and Ant+ (but it may need an Ant+ dongle.

I suspect I'll also be using it to look at Garmin Connect to see how poor my fitness journey is going.

Needs to be large enough to have a decent screen to view the video but not looking for a massive screen.

Is it a tablet I'm needing or something else? Not keen on Apple stuff, but I am sold in to Google (just as bad as Apple but not as expensive!). I'm not really sure what I'm needing to look at, so what would be recommended to be looked at please?

Thanks.
