This does sound quite cool!

Mobilism is a source for pirated ios apps, but it’s quite limited. I agree with the people mentioning pihole, but if you have to block ads on-device change the dns settings and/or use brave browser, which has the most adblock capabilities on iOS. Altstore is an alternative appstore (AltStore PAL in europe costs 1,50 a year in europe iirc) which has alot of cool apps and allows sideloading of ipa files on-device. I generally do recommend a pixel with grapheneOS, though I haven’t tried it myself yet.

Edit: Forgot to mention some of the downsides of AltStore, which includes needing to refresh the app once a week wirelessly or wired via a computer running Altserver

If you’re buying new just go for 4k, you don’t have to use it, but it’s nice to have for in the future or any gaming you might do soon. I’ve noticed that new it’s cheaper to buy 4k with hdr than 1080p without. I saw a Sharp tv with 4k hdr10 for 299€. If you really want 1080p any thrift shop will have some tv stacked in a corner, just look up the model number and you’ll see most of them that don’t have giant bezels are 1080p50, which fits your needs. Older tvs dont require internet for alot of features, or they won’t work with internet anyway, so you won’t miss much. Good luck in your search!
