With banking apps - it actually depends. I found out that in my country, most banks' apps (like, all the big ones except for one) don't require Google services, since requiring them would cut off a lot of users with Chinaphones (Huawei being the biggest example). The NFC payments in them are also their own implementation, independent from the Google one.
However, in case of at least one bank, the apk download link was hidden behind some dark patterns (ironically, less hidden than Signal's apk, lol), trying to instead direct people onto the national app store.
To have a massive wall of video, you need to have a home spacious enough for a whole spare wall first! I haven't seen a <1m screen that would fit in the kitchen corner my TV occupies on an arm - I don't even think a projector would work with a screen this relatively small. And where would the projector itself go if opposite of that corner is the couch/bed? Sit on my lap?
