Depends what you're using it for.
If it's for gaming, you might want to focus on refresh rate and response time. [Though I don't game myself, and hence will leave it to others to provide advice on that.] [I'm kinda guessing it's for gaming--that's the only reason I can think of to limit it to 1440; and even then, I'm not sure if you need to limit it in that way.]
But if it's for text work (reading and composing), I'd say 1440 would be far too low at those sizes. Instead, you want the highest pixel density possible in order to get sharp text. I find that MacOS, specifically, needs Retina pixel density (≈220 ppi) to look its best on text. That means either 5k@27", or 6k@32". Since you want at least 32", your only options would be the Dell 6k or the 6k Apple Pro Display XDR. The downside of the Dell, for me, is that I prefer glossy displays (more sharpness and vibrancy), and the Dell is matte only. [Yes, there is the 8k 32" Dell, which is glossy, but it's very finicky on Macs.]
