I would prefer a smaller phone for several reasons, the foremost being that where I'm not willing to go full luddite, I would like to de-emphasize my phone's presence in my life. So a phone that can more easily fit into a pocket makes more sense for me. However, the iPhone 12 mini just isn't much of an upgrade from my iPhone XS, so it doesn't make a lot of sense to buy one. The XS has been the most future-proof phone I've ever had. Would definitely have gotten a 12 mini pro if they made one. However, I will likely snatch up a 13 mini.
