dianthus, I am in same boat as I can't do the truly pointy toe, and even a lot of almond-tapered toes, either, and have narrow heels + bunion, and I don't even like truly pointy toes as a "look"--they still look kinda witchy to my eye.
So, I've identified a kind of "sleekness target" that includes both a slightly tapered, usually almond toe, plus other elements of the boot ) or sometimes shoe , how it hugs the foot, how the heel looks, and maybe the fit at the ankle, in terms of how the pants fall. Then I just have to try them on with targeted pants and see if they work to my eye.
So more sleekness or style in one element of the boot may allow more toe box leeway (though not always full-on round toe).
Then, that may why I've returned a lot of booties and other footwear, because I'm kinda pushing the envelope on toebox to get the style, but my feet have the final vote. I try to identify from photos and reviews whether it's likely to be comfortable, but it's really unpredictable. Some good brands with good reviews feel like rock boxes on my feet, and sometimes I find an unexpectedly comfortable fit when the photos looked iffy.
