To go back a little bit about models of phone. There are numerous brands other than the well known names you'll see in lots of reviews. In many ways the internet has made reviews even more useless than before as the big magazines/websites/toiletpapers tend to always put the well known brands at the top of their list (how much money do they make from the free equipment/affiliate linkes to an 800 quid unit etc.?).
Whilst not relevent to you, how many reviews have you looked at online...how many put the Galaxy 10/ipoo11 in the top three? Scroll down to number 10 and I bet you are still at a £550+ phone (probably last years version of the above!).
Randomly from the first page of reviews thrown up by google "The best phone right now is the Samsung Galaxy S10 Plus ". Is it? Really?
Back to your situation. Just like a camera....look for the one that has the features that you need, the features that you'd like if also available. The brand is far less important. A good photographer can take a good photograph with any camera......I can make a call or send a text with most cell-phones? You say you use whatsapp (do you really have so little interest in your privacy?) so you need a 'smartphone' ....won't be able to interest you in my BT Opal (the only Motorola phone I've ever owned) then
