We went through this recently and I concluded that in this price range Pixel phones have the best cameras by so far that if the camera is your main concern it distorts your options. Basically:
If you can stretch the budget / wait for a deal (Black Friday might do £50 off) get a Pixel 6A.
If you can get a used 6A in budget in the meantime, get that. Prices are sticky though.
If you can’t, try and find a refurbished 4A 5G for £200.
I don’t think there’s anything between those two prices that’s a better camera option than the 4A 5G. I see others on the thread are making suggestions in that range, so I’d certainly also say listen to them too. We considered then ruled out, but haven’t experienced the phones they are suggesting.
