Asus Zenphone? I’m not sure if it’s absolutely top notch specs but every review I’ve ever seen for it loves it. And it’s tiny. I love my phones as big as possible so I’ve never tried it but I’ve always wanted a bigger version of it so that I could.
Software support is quite a downside though. Asus is not great at supporting their Zenphones in comparison to other manufacturers. You only get around 2 years of OS updates (and 4 years of security updates? I guess it differs for each phone a little) The hardware looks great, but this was the reason to not buy it for me as I usually use phone for 4-5 years.
I went with the Pixel 8 Pro, I do really love the extra camera features, but the phone is just so big. I was using a regular Pixel 8 the other day and it was so comfy.
Of course it depends on body size and style of trousers you prefer. If you rock Cargo pants you will have no issues for sure :D
Ask a female friend for example, i guess lot of them cannot fit a modern phone into there pockets
