My phone requirements haven't changed much in the last ten years. I bought one of the first "phablet" phones with a comically oversized 5" screen that got me ribbed by friends ("compensating for something eh mate?") Now 5" is at the bottom of the available size range. I'm a smallish person/manlet and don't need a phone I'm going to drop, but I do need something big enough that I can reliably type on it.
I'll gladly support your endeavor. Thanks for taking the initiative.
edit: fine with me to make the phone thicc so it has a day+ battery life. A little thicker is far easier to hold on to, anyway!
edit2: I did own a Pixel 6 non-XL for about a day. It was large, but the bigger problem was that I found it incredibly topheavy, which made it difficult to hold on to. I swapped for a used 4a 5G, which is a well-balanced midsized device.
